Cameron Diaz popped up in Moscow this morning at a photo call for her movie Bad Teacher on the roof terrace of the city's Ritz-Carlton hotel. The actress is in the midst of a global press tour for the movie, which kicked off at an event in Madrid on Monday. Cameron will soon head back to the States in order to attend her Big Apple premiere in just a few days. Her costar in the upcoming comedy, Justin Timberlake, has been doing his fair share of interviews as well. Justin recently spoke to Playboy and addressed his relationship with ex-girlfriend Cameron. He said of their friendship, "It sounds complicated to everybody else, but it wasn’t to us. Honestly, the only thing I was worried about before I said yes to that movie was being asked that question. I knew at some point we’d have to promote the film and people would say, “Oh my God, that’s so weird that you two dated for four years.” I don’t know what else to say except the truth, which is that we’re friends. We don’t talk to each other all the time, but we respect each other, and on some level we’ll always love each other — but in our new capacity as friends."
