This may be too awkward to not watch.

Three years after breaking up, Justin Timberlake and Cameron Diaz are reuniting once again. The one-time couple of nearly four years are both set to star in Bad Teacher, a comedy from Walk Hard‘s Jake Kasdan.

Although the two technically worked on Shrek the Third together (and will both be heard on Shrek Forever After), this film will bring their working relationship to a different level. In Teacher, Cameron will play a gold-digging teacher who competes with a colleague for the affections of a well-off substitute teacher (Timberlake). I can just see the two of them - and Jessica Biel - on the red carpet together now…

Filming on Bad Teacher is scheduled to start this month. Jason Segel, Molly Shannon, Eric Stonestreet and John Michael Higgins will all co-star.
