Justin is rumored to have had a steamy weekend with The Daily Show star.

Whether they were started by the Twitter-happy hands of Lindsay Lohan or by JT's flirtatious ways, rumors of Justin Timberlake cheating on Jessica Biel are nothing new. The newest report, however, is extra juicy: US Magazine is claiming that Justin had a steamy, three day-affair with sexy comedian Olivia Munn from The Daily Show!  

According to the magazine, which has the story plastered on it's newest cover, Justin has been trying to end his relationship with Jessica for some time, despite the couple's lovey-dovey appearance this week at the Glamour Reel Moments event in LA. But, taking a page from the Kate Middleton guide to matrimony, Jessica is clinging on to him for dear life, even after his hook-up with Olivia last month.

Supposedly, sparks flew between Justin and Olivia, who has also been linked to Chris Pine and Bryan Greenberg, when she interviewed him in New York for his film The Social Network. According to a witness, the twosome was seen afterward out clubbing together and also at her hotel, and apparently Olivia thinks there is something more between the two of them than just the physical.  

Being the funny guy that he is, it makes sense that Justin would be attracted to someone who shares his comedic nature. But would he really throw everything he has with Jess all away for a weekend rendez-vous? Who knows, maybe Jess and Justin have jumped on the celeb bandwagon and have an open relationship as well. Did David And Courteney Have An Open Marriage?
