He's never afraid to walk around shirtless!

On Friday, Justin Bieber had a mini celebration of sorts as he and some friends hung out at his condo in Beverly Hills upon the arrival of his leopard-skin Audi from West Coast Customs.

Partying seems to be what the 20-year-old pop star does most these days, but those ways could land a popular night club in hot water.

Just a few days ago, Bieber was spotted with his hands on a Heineken while at Hollywood hot spot Bootsy Bellows, which is a violation due to his age. The club could be subject to a fine from the California Dept. of Alcoholic Beverage Control due to the incident and law enforcement are looking to step up their undercover efforts at the establishment.

Maybe he should party at his pad!
