Shirtless Justin Bieber showed off his abs as he returned to his hotel early this morning after a night of partying in London. It was a special occasion for Justin, who turns 19 today. He started off the celebrations on stage in Birmingham, and he shared a bit of nostalgia before his performance on his Twitter account, saying, "Gonna chill and get ready for this show. Last show as an 18 year old."
After his concert, Justin was ready to party, which he announced on Twitter, sharing, "Great show! Now gonna go celebrate 19! Thanks." Justin made the two-hour trek from Birmingham to London, and later hit the town with a group of friends at London's BLC club. The good times aren't over — Justin is reportedly planning a circus-themed party this weekend.
