Justin Bieber's 19th Birthday

The Party started  at 3am when he arrived back at his London hotel after performing in Birmingham on Thursday night  and partying with his rumored girlfriend Ella-Paige Roberts-Clarke Now, It was freezing in London, but Justin's choice of attire as he arrived at his  hotel was definitely odd, shirtless with bum showing pants...
Pull your trousers up! Justin's whole bottom was exposed as he made his way back into his London hotel
Letting it all hang out: Justin didn't seem in the least bit bothered that his trousers were barely protecting his modesty
Get inside now: Justin was ushered into his luxury hotel
