Despite a growing list of legal troubles — including two recent arrests and a brush with the law after hotboxing a private plane — it seems as though Justin Bieber has no cares in the world. The singer showed up to Diddy's DeLeon tequila launch party in Atlanta on Wednesday night and partied hard with rappers like T.I., Rick Ross, and Jermaine Dupri. It wasn't long before Justin was shirtless, save for a few gold chains. Also in attendance at Diddy's bash was his girlfriend, singer Cassie, as well as Justin Bieber's rumored new flame, Chantel Jeffries — find out more about her here. While the couple didn't pose for any photos together, Justin did share a snap with the group of hip-hop stars on Instagram. Justin has yet to heed the advice of his pal Miley Cyrus, who recently said that Justin should "buy a house and add a club to it" rather than going out.
