No white shirt, no problem for Justin Bieber.
After attending a Phish concert last night, the 19-year-old star hit the annual Cîroc White Party, being hosted by Kelly Rowland at Denver nightclub Beta—and within moments of being escorted to a private booth, Bieber and a buddy had shed their shirts.
A source exclusively tells E! News that a couple of SUVs ferrying Bieber and his entourage pulled up to Beta at around midnight and one staffer hopped out to inform club management that the singer and his small group wanted a private VIP area to hang out in, and were hoping to gain entry in as low-key manner as possible.
Security quickly escorted Bieber, a pal and his manager into the club through the kitchen and to a private table in the DJ booth, where Bieber and his friend quickly doffed their shirts.
After perching on the back of a couch and chatting with his buddy for a while, Bieber ultimately made his presence known to the rest of the club when he grabbed the DJ's mic and greeted the crowd.
Bieber was there for about two hours, until the party ended, the source said. He chatted with Rowland and rapper Chief Keef also stopped by the chat at one point.
According to our source, Bieber and his mates—all guys—had also requested that the club send a few of their VIP cocktail waitresses to join them in their booth for a while.
We hear that Bieber and his group were very nice and gracious, telling those at Beta who took care of them that they had a great time. Our source says that the teen asked if the club could stay open for another hour, but Denver law mandated the place close at 2 a.m.
And at the end of the night, Bieber left with his original group, with no waitresses along for the afterparty this time. Instead, the artist capped off the night with an early-a.m. session at Side3 Studios.
