Justin Bieber is in Atlanta for concerts tonight and tomorrow night – and we've got details on where he's been hanging out.

He and some friends stopped by Whiskey Blue, the rooftop bar at the W hotel in Buckhead, about 11 p.m. Monday night. He was wearing a denim jacket and baseball cap and his group enjoyed a round of beers while chatting happily with the staff, we’re told.

The concerts are sold out or pretty nearly there – but Cure Childhood Cancer is auctioning off VIP suite tickets and parking passes. Details here.
