Caught in the Act!
In the Big Apple, Justin Timberlake had a guys' night out with Diddy and a group of friends at the launch party for the fashion line Love by Isabel Adrian.

Rose McGowan was chatting up Joe Manganiello at W Hotels' Fashion Next party in N.Y.C. Before the actress arrived, the True Blood star worried that she may not remember him, even though they had done a table read together last year. But his fears were unfounded, and the two sipped champagne as they caught up, while checking out a performance by British singer Katy B.
