A Timeline of Christina Hall and Ant Anstead's Relationship — From Secret Romance to Shocking Split

New year, new man! The Flip or Flop star and the TV presenter's relations made their relationship public in January 2018, marking the moment with a photo of the couple taking a bike ride. They had clearly been keeping their romance under the radar for a few months, as Christina later said they met "at the end of 2017," and Ant revealed they celebrated a 6-month anniversary in April 2018.

Christina posted a sweet tribute to her new love on Valentine's Day 2018, and showed off his homemade gift for her: a picture frame. Ant echoed her sentiments, writing "My Valentine is a HOTTIE," on his Instagram Stories that day.

Ant gave his new love a tour of his "old stomping grounds" in London in March 2018. "Within moments of landing in the U.K. I couldn't help it..... we grabbed the G40 and gave @christinaelmoussa a tour of my world.... where I grew up, my school, my town," he said.

The HGTV host posted a heartfelt tribute to the Wheelers and Dealers star on his 39th birthday. "He has already grounded me in so many ways and I'm so grateful for him," she said, adding that he "is an amazing dad to his children and also great with mine, driven and talented, humble and kind, patient and a great listener, fun and hilarious, spiritual and to top it all off he's hot AF."

Time flies! Ant gushed over Christina on their six month anniversary, writing, "I've loved every second I spend with her!" He added that she is a "proper travel buddy," and also complimented her sense of humor and her ability to get his "British sarcasm."

Although they hadn't revealed any plans for marriage at the time, Christina and Ant did celebrate Prince Harry and Meghan Markle's nuptials in May 2018. Ant even admitted to texting the royal for advice on dating a "Yank." The famous newlywed's answer? "His reply will be kept a secret!" Ant said.

In a July 2018 PEOPLE cover story, Christina opened up about how she saw her future with Ant.

"I can see myself getting married to him," she said. "He's so down-to-earth, and we have so much in common. We basically do the same thing, so he gets what my world is like, and he's just rolled with the punches and handled everything so well."

That same month, after surprising her with a trip to Mexico for her 35th birthday, Ant made a grand gesture, having "I [heart] C" spelled out in sky writing above their oceanfront hotel.

He also posted a gallery of photos on Instagram to celebrate the big day. "HAPPY BIRTHDAY to this absolute LEGEND!!!! 35 today!!! @Christinaelmoussa you make me laugh every single day! You are crazy! In a good way! An inspiration! You saved me! Oh and not too shabby for 35!!!" he wrote.

The party of six vacationed together in Hawaii in August 2018, and braved a travel disaster, when, Christina revealed, they missed their flight because of a visit to urgent care and the impending arrival of a hurricane. "I guess Maui wasn't ready for us to leave," she wrote of the incident.

The couple celebrated their one-year anniversary in October 2018 with Christina revealing the story of how they first got together. "A year ago today [Ant Anstead] called me for the first time and we spoke for 29 mins two days later ... he FaceTimed me (I was thinking who FaceTimes?)," she wrote on Instagram, alongside a photo of them showing some PDA while in London. "Anyways I answered and we spoke for 2.5 hours ... two days later we met for the first time and we've been inseparable ever since."

In December 2018, Ant posted a photo of him and Christina sharing an "epic" dessert while "celebrating something special." Fans were quick to speculate that "something" was an engagement, noting in the comments that Christina's hands were conveniently cropped from the image.

The pair tied the knot in a winter wonderland-theme wedding at their home in Newport Beach, California, on December 22, 2018.

To pull off their surprise "I dos," the pair asked 70 of their closest friends and family members to meet at the house, where a charter bus would then transport the group to watch the Newport Beach Christmas Boat Parade. Instead, guests walked into a wedding. Under an altar in their front yard, the couple exchanged vows with their children close by.

Three months later, in March 2019, the newlyweds revealed they were expecting their first child together. 

The HGTV star posted a photo of herself hugging her husband and holding up a sonogram on Instagram, "Ant and I are so excited to announce #babyanstead coming this September!! The kids are all so excited to meet their new sibling," she wrote.

And baby makes 7! Their son, Hudson London, was born on September 6, 2019. 

"It's definitely been a big adjustment for all of us having a newborn around again. But it's so nice to be home, and we're all excited to figure out our new normal with the cutest little British baby," Christina said in an episode of Christina on the Coast that documented Hudson's arrival and aired in January 2020. 

In December 2019, the couple shared messages of love to celebrate their one-year anniversary. "1 year ago today! I still get emotional watching this! What a year it's been. I was 2 weeks pregnant with baby Hudson here and had no idea – ?. @ant_anstead I love you, our blended family and this life with you," Christina captioned their wedding video on Instagram.

Ant wrote his own note alongside a series of highlights from their wedding day. "Holy smokes!!!! A year ago! And What a year!? We have done enough for several lifetimes! I am blessed, I am lucky, I am loved, I am full, I am happy, I am yours. You saved me and you complete me!? you are PERFECT!!! My wife!"

On September 18, 2020, less than two years after their wedding, Christina announced in an Instagram post that the couple had split. 

"Ant and I have made the difficult decision to separate. We are grateful for each other and as always, our children will remain our priority," Christina wrote. "We appreciate your support and ask for privacy for us and our family as we navigate the future."

Christina and Ant finalized their divorce in June 2021. Both were granted joint legal and physical custody of their son Hudson, who was 21 months at the time. The divorce came 9 months after Haack announced their split.

During that summer, Ant began a new romance with two-time Academy Award winner Renée Zellweger. The two met and hit it off while working together on the set of the Discovery+ series Celebrity IOU: Joyride.

Following her divorce from Ant, Christina was confirmed to be dating Austin-based realtor Joshua Hall in July 2021. The new couple moved quickly and got engaged in September 2021 and married in April 2022. 

In April 2022, Ant filed for full custody of the couple's 2-year-old son Hudson London, PEOPLE confirmed.

In response to the filing, Christina told PEOPLE, "What Ant is doing deeply saddens me. If this was really about Hudson, as he says, this should have been handled privately with a private judge or mediation, as myself and my attorney have suggested."

"I have had my share of ups and downs but I am a good mom and I love my children with all my heart and I will always protect them," she added.

PEOPLE reached out to Anstead's rep for comment.

As per Ant's court order, filed on April 27 and obtained by PEOPLE, the Celebrity IOU Joyride host claimed that he has been the "primary parent" and that Christina has spent an "average of 9 full days each month over the last 20 months and an average of 7 full days per month in 2022" with their son Hudson.

Ant asked the court for Christina's "regular" custody schedule to be "alternating weekends, Friday at 4:00 p.m. until Sunday at 6:00 p.m. commencing May 6, 2022, in California only, and except for vacations."

"This will allow Christina's time to be stepped-up over the next several months to match the schedule she has with her other children," reads the filing. Christina shares son Brayden James, 6, and daughter Taylor Reese, 11, with ex-husband and Flip or Flop costar Tarek El Moussa. Anstead is dad to daughter Amelie, 18, and son Archie, 15, from his previous marriage to Louise Storey.

Ant has also requested that son Hudson does not appear in any paid media campaigns. As per Anstead's court order, he asked, "I be awarded sole legal custody of Hudson, or, in the alternative, for an order restraining both Christina (and me) from using Hudson or Hudson's likeness or image in any commercial endeavor, social media paid promotion, television or streaming program, or which might otherwise commodify Hudson without the express advanced written consent of both parents in writing."

The host went on to claim that Christina has featured Hudson in "paid advertisements to sell products" during the three of the five full days Christina had their son during March 2022. He also added that Hudson is "allergic" to one of the products used in the advertisement.

On April 28, a judge denied Ant's emergency request for full custody of their son Hudson because he failed to prove there were critical circumstances concerning the child and didn't give Christina enough notice.

The ex parte application is to show the custody situation is an emergency and needs to be dealt with urgently. Instead, following the judge's ruling, a hearing has now been set for June 28 to allow both parties to appear and make their arguments as to whether the requested change to the custody should be granted.

A rep for Anstead had no comment.

As the custody battle continues, Christina's husband Josh shared his support for his wife on Instagram on April 29.

"Never did I think taking on 3 kids from 2 other males would be easy," Josh began, referring to Hudson as well as Christina's son Brayden James, 6, and daughter Taylor Reese, 11, from her previous marriage to Tarek El Moussa.

"What I was sure of, the woman connected to them was worth it all. I am not these kids biological father, they have those. What I will be is the best example of a quality human being, always show them how to treat their mother with respect and support them in any way I can during their development."

"Coming from a split home myself, I know it's not easy on youngsters, but in todays world sadly, it's pretty common," he continued. "So Christina and I will always remain unfazed by any outside noise and save the kids from any unnecessary trauma."

Josh then goes on to praise Christina as a working mom, calling her "very driven" and a "positive influence" in her children's lives "while achieving success in anything she does."

"There is a lot that goes on in personal lives that isn't for public consumption, therefore not shared, kept private," he added. "So trust me as someone who likes to keep a low profile, no one except those directly involved knows jack about any situation more than them. 2 sides and the truth."

Josh concluded, "I will always protect her, keep her safe and no one will hurt her with me in the picture. She doesn't bother anyone, she deserves the same in return. I will ensure that's the case."
