A Justin and Cameron Meetup

People reporst that Justin Timberlake and Cameron Diaz had a little reunion at West Hollywood's Whiskey Bar in the Sunset Marquis Hotel. JT was there with Martin Scorsese and others when Cameron arrived around 1 a.m. She didn't join JT's table, but he went over to talk to her. A witness said: "They weren't kissing or holding hands or anything, but they were being very friendly."

And, they left together. You know, there's a reason that someone wrote a song called Breaking Up is Hard to Do.
