Justin Bieber enjoyed a guys' night out in Atlanta last night without any drama or legal woes.
The 19-year-old pop star, who's been at the center of much negative media attention recently, stepped out to celebrate the birthday of music producer pal Bangladesh at a local nightclub.
"Justin Bieber and about 10 to 15 pals came to the Tongue & Groove's Vice Mondays night in Atlanta," a clubgoer tells E! News exclusively. "He came for Bangladesh's birthday party. They came around 12:45 p.m. and stayed until 2:15 a.m."
The eyewitness says Bieber was only joined by male pals and there were no girls in his group.
"Justin came in wearing a dark gray hoodie, jeans, a baseball cap and had sunglasses on but pulled down and [was] carrying a Styrofoam cup," the onlooker dished. "He had been working at the studio late and came for the birthday party."
While Bieber's pals enjoyed Cîroc, Jack, Moët, five bottles of Dom Perignon, 12 Heinekens and 20 bottles of Voss water, the partyer says the Biebs didn't drink any of the club's alcohol and was "well behaved."
The eyewitness adds that Bieber laid low in a corner booth. "He had his back to the corner and his legs pulls up to his chest," they said. "He was keeping a very low profile. At one point, he laid on the sofa in the section like he was tired. He really didn't appear to be part of the party. He kept to himself. He seemed subdued. Maybe he was tired from working in the studio."
"They were hanging out and having a good time. They racked up a $3,000 bill," the clubgoer adds. "Everyone was partying, but Justin was definitely in the back almost like he was trying not to be noticed. He was definitely chilling out."
