Justin Bieber started his birthday celebration early last night and lost his shirt.

He was about to lose his pants, as these photos of the absolutely ripped singer, who celebrates his 19th birthday today (March 1), demonstrate. The Biebs was snapped outside his London hotel, with his pants hanging off his butt and sagging to the floor, after his gig and before he hit the party circuit. He eventually found a shirt and allegedly spent the night partying with his reported new fling Ellapaige Roberts-Clarke.

He's been seen squiring the aspiring British singer as he has been on tour in the U.K. She was reportedly his BRIT Awards afterparty date and the dating rumors began to fly, something she denied on Twitter. We think the lady doth protest to much, but that's just us.

On Feb. 28, Biebs was spotted showing off his guns, lats and pecs at his London hotel after his Birmingham show. He then proceeded to party like it was his birthday, since it was, with Ellapaige in tow. Cue the 50 Cent song, peeps.

While The Biebs is planning a circus-themed event tonight, complete with a ringmaster and clowns (cue the Britney Spears song), the festivities began at 3:30AM at BLC. Tay James and Ellapaige were with him, and they stayed out until 5AM. They grabbed some grub before returning to the hotel at 6:30AM.

Seriously, who knew The Biebs was so ripped? He looks better shirtless than he did in that hideous yellow hat and purple leopard print pants ensemble he rocked earlier this week.
