Cameron Diaz and Justin Timberlake back together?

London: Cameron Diaz and Justin Timberlake are back together for their new film `The Bad Teacher`.

"Initially, things were awkward there was quite a bit of tension and Diaz was quite nervous around Timberlake. But things went back to how they’d always been between the pair. They were fooling around off camera, taking the mick out of one another and generally goofing around. "There is undeniable chemistry. Word is that Justin and Cameron are on. It is the worst kept secret on set, and everyone, from the make-up artists to the canteen staff, are gossiping about them. They do make a really cute couple," mirror.co.uk quoted a source as saying.
