Josh Brolin, Eddie Murphy, Hugh Grant and More: Hollywood's Older Dads Club

Brolin is about to become a father of four!

The actor's wife Kathryn spilled her pregnancy news on Instagram on July 7, 2020, sharing a photo of herself posing outdoors with the couple's 20-month-old daughter Westlyn Reign.

As she and the toddler share a smooch, Kathryn, 32, bares her baby bump under a black crop top, finishing the look in a pair of denim shorts and a cowgirl hat.

"The Brolin's are a growin' !!" the entrepreneur captioned her post. "Our little December babe is on the way  ...🌱"

Josh, 52, left a cheeky comment on the post, writing, "Wow. That's amazing! Congratula ... wait ... WHAT?!?!"

Aside from Westlyn, Josh has two adult children - daughter Eden, 26, and son Trevor, 32 - from his first marriage to actress Alice Adair. Josh and Kathryn tied the knot in September 2016.

At age 89, Ecclestone is now a father of four. 

The former Formula 1 chief welcomed a son named Ace with his wife Fabiana Flosi, 44, on July 1, 2020, a spokesperson for Ecclestone confirmed to CNN.

Ace is Ecclestone's first son, and first child with Flosi. He is also dad to daughters Petra, 31, Tamara, 36, and Deborah, 65, from previous marriages.

The Mötley Crüe bassist, 61, and his wife Courtney, 34, welcomed their first child together, daughter Ruby, in 2019.

"What a great way to start off 2019 for Courtney and me," Nikki told PEOPLE.

Ruby is the first for Courtney while Sixx - whose given name is Frank Carlton Serafino Feranna, Jr. - is also dad to adult children Frankie-Jean Mary, Decker Nilsson, Storm Brieann and Gunner Nicholas.

Ruby was conceived despite the bassist having previously had a vasectomy.

Murphy, 59, and his girlfriend, Australian model Paige Butcher, recently welcomed their second child (and his 10th), but they don't have to worry about a shortage of half-sibilings to pitch in with babysitting.

The actor is dad to nine other children with five women, including five kids (four pictured at left) with his ex-wife Nicole Murphy.

The 67-year-old star shares two young sons, River Joe and Charlie Ocean, with wife Emilie Livingston, a Canadian dancer and gymnast.

"I keep doing the math, and keep extrapolating where they're going to be, and where I'm going to be," Goldblum told British outlet iNews of his kids. "And when I buy a watch, I wonder who's going to get it."

Though already dad to adult daughter Alexa Ray with ex Christie Brinkley, Joel was ready for round two when he and wife Alexis welcomed daughter Della Rose in 2015. Life got even sweeter in October 2017, when daughter Remy Anne was born to the 71-year-old musician and his wife.

"[Having children] makes all the difference because it's about them, not you," said the now-73-year-old musician of life with young Zachary and Elijah. "And it's the greatest thing you'll ever know." He continued, "People say, 'Well, I disagree, I don't want children' and that's fine - I would have said the same thing, until I had them. Then it was like, 'Wow this is it? Are you kidding me?' If I was 15 years younger, I'd have two or three more. Without question."

Lucky No. 8! The Rolling Stones frontman, currently 76, became a dad once more when he and ballerina-girlfriend Melanie Hamrick welcomed son Devereaux in December 2016. Despite being Hamrick's first, this baby is Jagger's eighth; the rocker's oldest is 49 and his next youngest is 20.

There's something in the water, it seems! The Rolling Stones guitarist, now 73, and wife Sally welcomed twin girls in May 2016 - making Wood's spouse a first-time mom and the rocker, who's a grandfather of 10, a dad for the fifth time.

Already dad to daughter Ireland from his first marriage to Kim Basinger, the 30 Rock star, currently 62, is trying his hand at daddy duty once again. Eight months after tying the knot in June 2012, Baldwin and wife Hilaria announced they were expecting a baby, welcoming daughter Carmen in 2013, son Rafael in 2015, son Leo in 2016 and son Romeo in 2018. They are currently expecting baby No. 5!

After spending years perfecting the role of doting dad on the big screen (Cheaper by the Dozen and Father of the Bride), life finally imitated art for the actor-author. Five years after marrying Anne Stringfield in 2007, the extremely private now-74-year-old surprised fans by confirming the couple had welcomed their first child in 2013.

It's all girls for the Die Hard star, who welcomed daughter Mabel in 2012 and daughter Evelyn in 2014 with wife Emma. But Willis, now 65, is already a pro at fatherhood: His decade-long marriage to Demi Moore produced daughters Rumer, Scout and Tallulah, all of whom he is very close to.

His role as protective papa in Meet the Parents was certainly no stretch. The Academy Award winner, currently 76, is a father six times over. Drena and Raphael are from his first marriage to Diahnne Abbott, while he has twin sons, Julian and Aaron, with ex-girlfriend Toukie Smith. He and estranged wife Grace Hightower are parents to son Elliot and daughter Helen Grace.

Despite being a father to five kids from previous relationships and a fairly new grandpa, the rocker, now 75, was eager to expand his brood with wife Penny Lancaster. His wish came true when the couple welcomed their first son, Alastair, in 2005, before getting married in 2007. In 2011, they got double the blessing when son Aiden was born.

After almost 30 years of marriage - and seven children together - the actor and wife Robyn called it quits in 2009. Months later, the star announced that he and model girlfriend Oksana Grigorieva were expecting a baby together. Daughter Lucia was born in October 2009, only five months before the couple's relationship took a tumultuous turn and ended. In 2015, he moved on with equestrian and screenwriter Rosalind Ross; in January 2017 they welcomed now-64-year-old Gibson's ninth child, son Lars.

The actor, currently 76, first dived into daddy duty when he and ex-wife Judy Helkenberg welcomed son William in 1971. Following their divorce, and the birth of daughter Alectra in 1995, the actor began dating Steffanie Sampson, which eventually led to his third go at baby bliss when son Luke was born in 2010.

It's lucky number seven for the Oscar-winning director! When he tied the knot with wife Christine in 2004, the actor, now 65, was already a father of four adult children - Anne, Lily, Joe and Liam - from previous relationships, but that didn't deter the veteran family man from adding three more kids to the mix: including Cayden, Hayes and Grace.

It was a match made in Hollywood heaven when the most eligible bachelor, now 83, met actress Annette Bening. Shortly after the birth of their daughter Kathlyn in 1992, the couple tied the knot and went on to welcome son Benjamin in 1994 and daughter Isabel in 1997 before the birth of their fourth - and final - child, Ella, in 2000, the same year the actor celebrated his 63rd birthday. "He's a fantastic dad. He's just enthralled, very thoughtful, very communicative," Bening has said.

Divorced with one son, Cameron, the actor scored a second chance at fatherhood when he married actress Catherine Zeta-Jones in 1998. The couple would go on to welcome son Dylan in 2000 and daughter Carys in 2003, and the doting dad, now 75, is grateful for the gift. "I never anticipated starting a family and the joy of raising kids at my age," he has said.

Following the death of his first wife Linda, with whom he had four kids, including designer Stella McCartney, the former Beatles member began a relationship with then-model Heather Mills, making it official with their 2002 wedding in Ireland. Less than a year later, he became a dad for a fifth time at the age of 61, when the former couple's baby girl, Beatrice, was born.

After almost 17 years of dating, the late-night host and his partner Regina took their relationship to a whole new level in 2003 with the birth of their first child, son Harry. The funny guy - who was 56 at the time - and his longtime love eventually tied the knot in 2009, with their then 5-year-old son at their side.

The now-83-year-old award-winning actor's greatest role - dad! - came when he and his wife Sandra Knight welcomed daughter Jennifer in 1963. But it was his relationship with former flame Rebecca Broussard who made him a later-in-life dad after the couple had daughter Lorraine and son Raymond who was born the same year his famous father turned 54. Nicholson is also dad to Honey Hollman.

Three years after tying the knot with Kimberley Buffington in 2004, the former Hollywood heartthrob, now 66, plunged back into parenthood when the former couple welcomed twins Thomas and Grace in 2007. This was 15 years after the birth of son Jack, his only child with ex-wife Meg Ryan.

In June 2020, Quaid quietly wed Laura Savoie.

Dad to six children at the age of 63, Eastwood didn't envision more kids in his future - until he met wife Dina. A few weeks following their Hawaiian wedding, the couple - who are now divorced - discovered they were expecting their first child together - and Eastwood's seventh! Daughter Morgan was born in 1996, when the actor-director was 65.

Following a slew of relationships - and three children - the iconic late-night host tied the knot and settled down with his seventh wife Shawn. At the age of 65, he would return to double the diaper duty when the couple welcomed their first son Chance in 1999, followed only a year later by the birth of son Cannon.

Just like his Oscar award for Best Actor (he won in 1992 for Scent of a Woman), fatherhood came later in life for the now-80-year-old Hollywood legend. He welcomed his first child, daughter Julie, in 1989 at age 49. And in 2001, he and then girlfriend Beverly D'Angelo were blessed with twins Anton and Olivia.

When son Jett tragically passed away in 2009, having more kids was the furthest thing from the actor, now 66, and wife Kelly Preston's minds. But, less than two years later, the couple surprised everyone with news that they were adding another baby to their brood (they are also parents to adult daughter, Ella). Just three months shy of his 57th birthday, Travolta and Preston welcomed son Benjamin in November 2010.

A little over one year after welcoming daughter Tabitha in 2011, the now-59-year-old actor and his on-and-off-again girlfriend Tinglan Hong added another baby (a son!) to their brood. He and now-wife Anna Eberstein have three children of their own, born in 2014, 2015 and 2018.

The rocker, now 60, received an early Valentine's Day present when daughter Lula Rosylea arrived in February 2013. But this isn't Adams' first time changing diapers: he and girlfriend Alicia Grimaldi are also parents to daughter Mirabella Bunny.
