There is a lot of interest around Justin Timberlake and Cameron Diaz's new film, Bad Teacher, as the former flames are starring opposite each other for the first time since their split.

In the film, Cameron's character tries to seduce a naïve student teacher played by JT and we can't help but hope some sparks will fly between the two.

Photos of the pair on set show that Cameron seems pretty happy about the whole thing but that Justin looks more than a little worried.

Do you think anything will happen between the former couple or is JT just too into his Señorita, Jessica Biel?
