Justin Timberlake Cheated on Jessica Biel with Olivia Munn?!

Justin Timberlake can change his Facebook status to “It’s Complicated.” According to the new issue of Us Weekly, the Social Network star cheated on girlfriend Jessica Biel with actress Olivia Munn during a three-day fling this past September

Olivia, 30, is a correspondent on The Daily Show, and will also appear in the upcoming NBC show Perfect Couples. She first met Justin, 29, at MySpace event on Sept. 26. A source revealed that the two exchanged phone numbers and then Justin ”started chasing her immediately.”

Olivia reportedly resisted him, saying she wouldn’t go out with him if he was still dating Jessica (28), but Justin ”has been telling people it’s over with Jessica, even though “the reality is he’s just doing it behind her back.” Once Olivia thought J and J broke up, she was “openly affectionate” with him at her hotel, the Gansevoort Park Avenue NYC, on Sept. 27 and 28. The rumor gets even juicier as the insider says the two ”had amazing sex” that night. Yowza, TMI. Why would anyone who knows that much detail be talking to Us Weekly?

Justin’s rep strongly denies the story, and Olivia’s doesn’t comment on her personal life. Justin and Jessica have been dating since 2007, with multiple stories of them breaking up and getting back together. Do you think this one is true?
