WILLIE NELSON is in a new "web exclusive" from Conan O'Brien's website, TeamCoco.com . . . where he auditions for the part of Gandalf in the second "Hobbit" movie. (???) The whole thing is pot-themed, of course.

Chris Brown and Drake have been feuding for a while now.  Last summer, their beef even instigated a HUGE, bottle-throwing nightclub brawl, which may or may not have been over RihannaBut that doesn't mean they hate each other's music.

Chris was seen DANCING to Drake's song "Started from the Bottom" at some club in New York earlier this month.  It's probably safe to assume he DID KNOW it was a Drake track.  

From the get-go, NOBODY believed Ray-J's new song "I Hit It First" wasn't about Kim Kardashian. even though he continues to deny that it is. Well, he just released the video, and it's obvious that he's still trying to play us because his co-star is a BLATANT Kim Kardashian look-alike.
