justin bieber nba mascot NBA All Star Game: Justin Bieber, Rihanna, Beyonce and more cheer from the sidelinesAfter cementing his MVP status in the NBA Celebrity All-Stars game, Justin Bieber took his place on the sidelines to watch the real NBA stars hit the court (and to be accosted by a mascot). No one can resist the Biebs.

By his side for the evening? Rihanna — who rocked her half-time performance with Drake and Kanye West.

There were plenty of celebs on hand for the big East vs. West hoops showdown including Beyonce, Jay-Z, Lil’ Wayne and of course, Jack Nicholson.

The Biebs had his charm going full force, as usual. Even Lenny Kravitz shared a laugh with the teen dream.

Jack Nicholson has cemented his role as a sideline fixture for Lakers’ games year round, so it’s no surprise to spot him in the audience. In case you don’t recognize his guest, it’s sports reporter Jim Gray, who was pulled from his duties on a Golf Channel broadcast over the weekend. We imagine he’s not too upset with the way his weekend panned out… we’d call that an upgrade.
