Justin Timberlake Cheating on Jessica Biel?

This doesn't sound good.

He could be in trouble!

Justin Timberlake's been caught red-handed getting too close to another woman, and now it sounds like he could have been exploring his feelings with Cameron Diaz as well. Do you think it's possible that he's cheating on Jessica Biel? The evidence is mounting!

The first story was all about Justin Timberlake and a pretty waitress, with whom he was supposedly canoodling. Insiders say that the woman, originally called a "go-go dancer" in the press, had her hands up his shirt, but others say that she's not his type.

Rumors continued that Justin wants to act like he's single, so he is. That's pretty much the scoop, and Jessica Biel either doesn't care or doesn't want to think about his transgressions.

Now OK! magazine claims that Cameron Diaz pushed to have Justin Timberlake cast in Bad Teacher, because she knows there will be a ton of love scenes in the film. Via our partner:

"Cameron's such a bad girl: she made them rewrite the love scenes so that they're even juicier - and longer," a source revealed to the tabs. "She doesn't want to stir up trouble. But you know, she's been cheated on - Justin cheated on her. She may not hold to the letter of the law when it comes to Jessica."

Insiders claims that Jessica's pretty nervous about Justin's film work alongside Cameron, considering her rumored intentions.

"When Justin made it clear he was doing the movie with or without Jessica's support, Jess swallowed her pride and did the unthinkable - she pilfered Cam's cell number from Justin's phone and called her to bury the hatchet," the source said.

"Jessica said she was thrilled Justin was working with someone of Cameron's caliber and thanked Cam for going to bat for him."

Do you believe the rumors? Since there always seems to be something weird going on with Jessica and Justin, I do. I think that Cameron did push for Justin, and maybe that's because she likes working with him. Who knows? Maybe she really likes working with him, if you know what I mean.
