Justin Timberlake & Jessica Biel's Road to the Altar

In 2007, their romance was exciting and new: After a January split from Cameron Diaz, Justin Timberlake was spotted chatting up Jessica Biel at a Golden Globes afterparty. Six months later Biel joined the singer on tour, and the duo were snapped snuggling onboard a sightseeing cruise in Oslo, Norway.

Turning his 2007 tour into a romantic getaway, Biel followed Timberlake to Goteborg, Sweden, where the pair stepped out hand-in-hand. “It’s so funny how it really has become such a crazy, crazy world,” she later told Parade.com of the pair’s paparazzi attention. “You really do just have to laugh at everything.”

In a rare moment of PDA, the ultra-private couple was snapped smooching during a sweet stroll through Rome’s Piazza di Spagna square in September 2008 – more than a year into dating. “I get pretty romantic around her,” Timberlake gushed to Oprah Winfrey.

In Italy, Biel and Timberlake looked just like any couple, touring the Colosseum and shopping in Rome’s Via Condotti neighborhood.

Here comes the bridesmaid! Timberlake met Biel’s onscreen family when he served as her date to 7th Heaven costar Beverley Mitchell’s 2008 nuptials, held in the Italian coastal town of Ravello.

Just before the Thanksgiving holiday in 2008, Timberlake and Biel squeezed in some furry family time in L.A. with their dogs, her pit bull Tina and his two boxers Buckley and Brennan. “[It’s my] one sparkly present,” the normally tight-lipped actress shared with British GQ about her relationship. “And I don’t want to open it in front of strangers.”

After making a surprise appearance on Saturday Night Live, Timberlake and Biel kept up their laugh fest with a stroll in New York City on March 8, 2009.

Justin scores again! Timberlake couldn’t help but get frisky with his lady love while on the “Kiss Cam” at an April 2009 L.A. Lakers game. “We’re not actually that much of exhibitionists,” he said on Jimmy Kimmel Live. “[But] they cut to Dustin Hoffman and his wife … and he planted an open-mouthed kiss on her that was just kind of award-winning in its own way. And then it cut to us and I was not to be outdone, OK? So I mounted my girlfriend in front of 18,000 people.”

Though they made a stunning red carpet pair (here at the 2009 Metropolitan Museum of Art’s Costume Institute Gala in New York), the couple made the most of their time off-camera. “We just hang out at home,” Biel told Parade. “You have to have a real life because of the kind of crazy Hollywood stuff that you can get wrapped up in.”

Biel and Timberlake stayed in sync with one of their favorite activities – working out – in May 2009 in New York City.

The couple had domestic bliss in the bag as they prepped for the Fourth of July in 2009 at a Brentwood, Calif., Whole Foods. “She’s amazing. She’s so down-to-earth and her family is great,” Timberlake’s mom Lynn Harless said of her son’s longtime love, calling Biel “one of us.”

Putting rumors of a breakup to rest, Timberlake visited Biel in Vancouver in October 2009, when the actress began shooting The A-Team. Out and about, the “affectionate couple” grabbed lunch at a vegetarian eatery and watched a screening of Where the Wild Things Are.

The couple kissed and danced the night away to celebrate Timberlake’s William Rast collection during New York Fashion Week in February 2010, then sat front and center at the Paris68 show.

Putting their love on display, Biel and Timberlake caught a performance of Broadway’s Memphis in May 2010 – where “Justin kept his hand on Jessica’s back the whole time,” a show insider told PEOPLE, and met with castmembers backstage.

Timberlake had Biel’s back at the October 2010 debut of Glamour magazine’s Reel Moments series, which featured a short film directed by the actress. Days later, a source shot down rumors the singer had strayed with TV personality Olivia Munn, saying, “Justin and Jessica are doing fine.”

The Social Network star only had eyes for Biel during the Feb. 27, 2011, Vanity Fair Oscar afterparty, but just weeks later, the couple announced their split. Rumors swirled that Timberlake had already moved on with Friends with Benefits costar Mila Kunis, while Biel was linked to Gerard Butler that June.

By August, the duo appeared to be together again when they were spotted bike-riding in Toronto and, the following month, enjoying a P.D.A.-filled holiday in Colorado. “They always remained friendly after the split and spent time together,” a source said.

“She is the single-handedly most significant person in my life,” Timberlake said of his lady love, whom he asked to marry him during the couple’s annual vacation to Montana in December. Three months later, the public got their first view of Biel’s engagement ring during a lunch date with her fiancé in March.

Weeks before their engagement party, Biel planted an affectionate peck on her man – and put her megawatt sparkler on display – during a May 12 L.A. Lakers game at the Staples Center. “I had no say whatsoever [on the ring],” she told InStyle in August. “He is fearless in his choices and has a real eye for design. And I’ll be honest: He has better taste than I do.”

Following a September bachelor party, Timberlake was back in his bride-to-be’s arms at Variety‘s Power of Women event on Oct. 5, where Biel was honored for the work done by her non-profit organization, Water. The kissing couple made it official two weeks later, tying the knot at an Oct. 19 hush-hush ceremony in southern Italy.
