Justin Timberlake and Cameron Diaz are currently filming their new flick, Bad Teacher, and - of course - rumours are beginning to circulate that they are getting it on, if you know what I mean *winks*. JT is currently attached to Jessica Biel, but hey, that hasn't stopped these Hollywood folk before *looks in the direction of Tiger and Jesse*. A source on set had the following to say; "Initially, things were uber awkward (Bruno, is that you?)... but after two days 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. On day five, they snuck off for a secret lunch... and this has been happening pretty regularly".

Now, you can believe this if you wish, but it sounds more like someone is trying to rile up a bit of publicity for the film so that when it opens, we'll all flock to the big screen to watch the 'chemistry' unfold. Justin wouldn't do this to Jessica, especially not after what happened with Britney.
