They broke up back in 2007, and now Justin Timberlake and Cameron Diaz are reuniting - on the big screen, that is.

Reportedly, the pop artist has landed himself a part in Cameron’s upcoming comedy “Bad Teacher” in which he’ll play a substitute teacher who is also Diaz’s character’s love interest.

Set to start shooting in Los Angeles later this month, the film costars “Saturday Night Live” alum Molly Shannon, Jason Segal, Lucy Punch and “Modern Family’s” Eric Stonestreet.

Timberlake and Diaz dated for four years and after their split Justin began dating actress Jessica Biel.
