Shortly after Justin Timberlake and Jessica Biel's break-up, everyone was quick to point out how cozy he and his Friends With Benefits co-star Mila Kunis had become.

Being friends with your co-worker is one thing, but have you seen their chemistry how close they've been at all the award ceremonies lately?

A source close to Justin claims that there is nothing going on between the two: "They're not in a relationship. They star in a movie called Friends with Benefits but they're just friends. That's it. They are not together." Sounds awfully familiar to what sources claimed about Brangelina when Mr. and Mrs. Smith came out...

As for those rumors claiming Kunis was the downfall of Justin and Jessica's 4-year relationship?

"Mila had nothing to do with their break-up. In fact, no one came between them. They decided their relationship ran its course and it was time to move on," the source said.

The film is due out in theaters this July.
