Hollywood superstar Cameron Diaz is "thrilled" ex-boyfriend Justin Timberlake has been cast as her new love interest in the picture "Bad Teacher", because his on-set antics are keeping her entertained. Cameron is starring as a junior high school teacher who sets out to steal a colleague's boyfriend, played by Justin. The actress dated the pop star for almost four years until they split in 2007, and Justin has since found love with sexy Jessica Biel. Cameron told Access Hollywood's Billy Bush, "We're thrilled to have him. He's the best person for the job. He's going to be hilarious. He's clearly a very talented comedian, look at his 'Saturday Night Live' (skits). He's fantastic; he's going to be so great. "We just had our first day of shooting yesterday with Jason. And we just laughed all day. It's so wonderful, I'm so excited."
