While coming face-to-face with an ex partner could prove to be awkward for some, it certainly doesn't seem to be the case for Justin Timberlake and former girlfriend Cameron Diaz.
The pair, who split up three years ago after a four-year romance, have teamed up to costar in upcoming comedy Bad Teacher.
In the first-released photo from the new film, the pair are seen giggling away as they get into character as two teachers who strike up an unlikely romance.
"They obviously know each other really well," director Jake Kasdan tells Entertainment Week.
"They're good friends, and they're both incredibly funny people. I couldn't be more excited about it," he adds.
Filming started in Los Angeles two weeks ago and the movie is expected to be released in 2012.
