Bad Teacher, an upcoming 2011 comedy movie directed by Jake Kasdan stars ex-couple Cameron Diaz and Justin Timberlake.

According to Cameron, working with Justin was comfortable and there was no awkwardness because they already know each other.

In Bad Teacher, Cameron is Elizabeth Halsey who is a foulmouthed, poor Chicago teacher who wants so much to marry her wealthy fiancé and get away from the school she teaches in. But when he dumps her, she sets out to win over a rich substitute teacher Scott Delacorte played by Justin Timberlake.

Other casts include Lucy Punch as Amy Squirrell who also runs after Scott (Timberlake), and Jason Segel who plays Russell Gettis, a gym teacher who likes Elizabeth (Diaz).

The movie is scheduled for release on June 17 in the UK and June 24 in Canada, and USA.
