12 Celebrity Couples Who Met On Set

Where they met: The duo met in 1998, when they were both cast in That '70s Show (Kunis was notably only 14 years old at the time). They didn't officially begin dating until 2012, after Kutcher separated from Demi Moore. Length of relationship: They started hanging out (romantically) in 2012, got engaged in 2014 (the same year they had their first child, Wyatt), and got married in July of 2015. Cutest moment: It recently came out that Kunis and Kutcher started their romance as hook-up buddies. The actress told Howard Stern of their first hook-up, "For the first time ever, [he] took my breath away. Like that's the best way I could describe it. Long story short, I didn't leave 'til the next morning."

Where they met: In 2006, Tatum and his now wife co-starred in dance flick Step Up. Although they didn't begin dating until after shooting wrapped, the film clearly ignited a spark. Length of relationship: The duo got engaged in the fall of 2008 and married in July 2009 at Church Estates Vineyards in Malibu, CA. Their first kid, daughter Everly, was born in 2013. Cutest moment: Basically every moment with these two is the cutest moment ever. But one of the most memorable came earlier this year, when they celebrated Father's Day together. In an Instagram post, Dewan-Tatum shared an adorable snap and wrote, "We couldn't love this daddy more! You are all heart and we are so grateful for you every day."

Where they met: Craig and Weisz came together while filming the horror flick Dream House in 2010, following Weisz's breakup from director Darren Aronofsky. Length of relationship: After meeting in 2010, the pair married in June of 2011 in a private ceremony attended by only four guests, including the duo's children from previous relationships. Cutest moment: Although the couple always look lovely together on red carpets, we don't really know anything about their relationship and they don't end up in the media very often. Last year Weisz sweetly told More Magazine, "He's just too famous. It would be a betrayal. You have to protect your marriage. When you're young, you tell your girlfriends everything. One of the great pleasures of not being an adolescent is that you don't have to share everything. When you're married, that door closes. The audience goes, and you're in your own life."

Where they met: Sorry, ladies. Gosling met his romantic match in 2011 when he worked with Mendes on The Place Beyond the Pines.

Everything else is mostly a mystery with these two. Cutest moment: After the couple's first daughter was born, Gosling told E! in a rare share, "I know that I'm with the person I'm supposed to be with." As for why? "She's Eva Mendes," Gosling notes. "There's nothing else I'm looking for."

Cutest moment: Back when they first started dating, Kartheiser explained to US Weekly exactly how important it was for him to make things work. "I'm a really lucky guy," he said.

All the other stuff is good, like FaceTime and the texting, [but] I love seeing her. You gotta make the flight!"

Cutest moment: During an appearance last year on Watch What Happens Live, Moyer described falling in love with his wife. "We met screen testing for the show," he said. "We were both single at the time, and there was just this kind of spark. I didn't see her for three months, and she had gone from having dark hair to this beautiful blond, and I had gone from being blond to this dark vampire. By day three or four—oh, this is going to sound so syrupy—but I knew I wanted to spend the rest of my life with her. It was within seconds, really, and it just became a thing."

They've since added two kids to their family. Cutest moment: Gellar recently offered some sage advice on how to make marriage last. She told People magazine: "Take the ten minutes—put the phone down. Have a cup of coffee together. Walk the dog at the end of the night. Read a story with your kids. Make the most of the time that you have. We are all pulled in so many directions, so make sure that, whichever one you are focusing on, you're present."
