Sources tell the New York Post's Page Six that at a Friday pre-Grammys soiree fronted by Rolling Stone and Justin Timberlake, Grey's Anatomy cast members T.R. Knight, Kate Walsh and Sara Ramirez were chilling in the VIP section when a bodyguard for Sean Combs told them to vacate their table, and thus make room for Puffy's posse. "This guy... started demanding, 'Get out! Get out now! Move it!' T.R. was furious," an eyewitness tells the paper, adding, "I don't think Puffy knew who T.R. was." After Knight exchanged words with Combs, the Grey's trio were led to another table.

A friend of Combs' tells the Post, "He wasn't aware of what was going on," while a rep for the singer says, "There was no [altercation]." "There was no altercation," eh? We've heard that one before.
