…for a movie, that is. The former flames are working on their first project ever since they split up in 2007.

According to IMDB, Bad Teacher is a comedy about a junior high teacher (played by Cameron) who, after being dumped by her sugar daddy, begins to woo a naïve colleague (played by Justin)—a move that pits her against a well-loved teacher. |

Much hype surrounds the reunion between the two former lovers and all eyes will be on how Justin and Cameron will interact and potentially reignite romantic flames while filming. The two seriously dated for four years, and Justin is now with Jessica Biel.

Shooting for the movie began last weekend in LA, and the two exes seem very professional and in good spirits. Also on set is comedian Jason Segel, and so far the only body language we see between Timbo and Cameron spells “hard work.”
