Behind the split

Signs of the split between Justin Timberlake and Cameron Diaz have been appearing for weeks, according to reports. The former couple hadn't been seen together since December 16, when they were spotted at the party for Timberlake's SNL hosting gig. Timberlake then spent Christmas with his family in Tennessee, while Diaz spent the holidays in Vail. "He called me around Christmas to say they had broken up," said a friend of the SexyBack singer. "I don't think she's so much into the scene like he is. He's really young and he likes to go out. [He] hasn't been into her for a while." At the opening show of Timberlake's new tour on Monday night, the singer told the crowd, "Sometimes love isn't so easy."
