According to TMZ, Justin was partying with NFL star Johnny Manziel, Floyd Mayweather, Tyrese, and Tyga at his Beverly Hills condo when the po-po came because of loud music complaints. Chantel Jeffries was there as well.
Justin is pretty much proving he's the worst neighbor ever...as if we needed more proof of that or something. He just moved into this new place a month ago, and the police have been called numerous times before this throwdown too.
The kicker? Bieber's on-again and off-again girlfriend Selena Gomez had to actually call the cops last night too, because she thought someone broke into her Calabasas home. Coincidence?
