Not long after her split from Brad Pitt, Jennifer Aniston hit it off with her co-star in the 2006 comedy The Break-Up, Vince Vaughn. While their romance only lasted for about a year, it seems that they still think pretty highly of each other. Speaking to Playboy in 2015 (as reported by HuffPost), Vaughn said that while Aniston was "great," he wasn't as big of a fan of the paparazzi attention involved in dating a super-famous woman who was just out of one of the tabloids' favorite relationships.

Unlike most of the other couples on this list, Matt Dillon and Cameron Diaz were already an item by the time they worked together. The actors met in 1995, started seeing each other in 1996, and in 1998, they appeared opposite each other in the gross-out comedy There's Something About Mary. But soon after it arrived in theaters, they broke up. According to Dillon, distance was a factor.

"Look, I loved her and we were very close, but it just ran its course," he told Rolling Stone. "We're both actors, she was living in L.A., and I was living in New York, and I didn't want to commit to moving out there. But I don't want to say it was about any of those things. It just ran its course." For snaps of duos in the early days, check out Adorable Photos of Celebrity Couples When They First Got Together.
