Bieber Fever: Justin Was Booed at a Knicks Game, Might Perform at Wrestlemania and Has a New Collaboration with Sean Kingston

JUSTIN BIEBER was at a New York Knicks game at Madison Square Garden on Wednesday night . . . but the fans there weren't impressed.  When they showed him on the JumboTron, the crowd erupted in boos. 

--The announcers said the boos were mixed with cheers, but in the video all you can hear are the boos.  It was so loud that the players and coaches were looking up to the scoreboard to see what was going on. 

 (--Man, that's not cool.  Sure, he's rich, famous and living a life we can only dream of . . . but he's a 16-year-old kid, for crying out loud.  There's no reason for an arena full of people to boo him like that.) 

--The cold reception is kind of surprising coming from basketball fans . . . since basketball culture is so closely intertwined with hip-hop culture.  Don't they realize that rappers LOVE this kid? 

--Regardless, it seems that Justin and his people are dead-set on pushing him out of his teen-girl comfort zone.  There's unconfirmed talk on the World Wide Wasteland that Justin is in negotiations to perform at WrestleMania 27 on April 3rd. 

--By the way, Justin is featured on a new SEAN KINGSTON track called "Won't Stop".  (--It's on Sean's brand new mixtape "King of Kingz".  It's actually a cool track.  You can check it out, here.)
