In 1998, she locked lips with her That '70s Show costar Ashton Kutcher—on camera, no less! "I was like, 'Oh, he's so cute, it's the Calvin Klein model!'" Kunis later told People. "Then I was like, 'I have to kiss him?' I was so nervous and uncomfortable. I had the biggest crush on him." When Kutcher found out, he couldn't believe it. "I'm the first guy she kissed? Oh my god, I had no idea!" he told the weekly magazine later that year. "I'm so glad I didn't know that or it would've been too much pressure."
The comedy aired on Fox from 1998 to 2006, during which time they dated other people.
Kunis began romancing Home Alone star Macaulay Culkin in 2002. Seven years later, after denying engagement rumors, the actress told BlackBook that she wasn't keen on the idea of marriage. "Not to say that I don't believe in it, but it's just not something that's important to me," Kunis explained.
The unlikely couple called it quits in late 2010 but kept the news of their breakup secret until early 2011. "The split was amicable, and they remain close friends," Kunis' rep said at the time.
Even though they weren't dating at the time, Kunis spoke fondly of Kutcher. "People think Ashton has changed," she told Parade in October 2007. "He's still the same old goofball that he used to be."
Kutcher, meanwhile, dated a number of women during his time on the show. According to January Jones, however, the TV star was a terrible boyfriend. "He was not supportive of my acting," the Mad Men star told GQ in 2009. "He was like, 'I don't think you're going to be good at this.' So, f--k you!"
In spite of their 16-year age difference, the A-listers became notorious for their PDA-packed outings and gushy tweets. In November 2011, Moore announced plans to divorce the Two and a Half Men star.
"It is with great sadness and a heavy heart that I have decided to end my six-year marriage to Ashton," the Margin Call actress said in a statement. "As a woman, a mother and a wife there are certain values and vows that I hold sacred, and it is in this spirit that I have chosen to move forward with my life."
Thirteen months later, Kutcher filed for divorce in L.A. Superior Court, citing irreconcilable differences. When Moore filed a response two months later, she too cited irreconcilable differences. Unlike Kutcher, however, she asked to receive spousal support and compensation for her attorney's fees.
During their drawn-out divorce proceedings, Kutcher began spending more time with Kunis—and by the spring of 2012, it was clear that their friendship had evolved into a romance. Still, he was hesitant to say anything about their courtship, telling Elle, "People will fill in the blanks however they want."
As tensions with Moore reached an all-time high, Kutcher—whose divorce was finalized in November 2013—became less inclined to discuss his personal life. "You know, I've learned the hard way how valuable privacy is," he said. "And I've learned that there are a lot of things in your life that really benefit from being private. And relationships are one of them. And I am going to do everything in my power to have this relationship be private."
Of course, the former co-stars didn't exactly hide their mutual affection for one another. During their PDA-packed trips around the globe, they hung out with Princess Beatrice and David Clark. After attending their siblings' respective weddings in December 2013 and February 2014, Kutcher decided to pop the question.
For Kunis, marrying Kutcher is a dream come true. "Listen, in five years I do hope to have a family, and, you know, who knows?" she told Interview in August 2012. "I've always been a big proponent of not working for the sake of working, because I don't want to work for the rest of my life—I want to live."
