This lad looks like he's been celebrating his birthday in style. Harry Styles stepped out last week to ring in his 19th birthday and certainly didn't leave anything out on the streets of Soho as he and his crew partied until 4am, calling in around a number of the London area's trendiest hotspots. The One Direction member turned up with a lovely looking blonde lady, and left with her some hours later - though admittedly the pair of them weren't looking quite so lovely at that point.

It was a hard day's night for Harry Styles and his mystery blonde friend

The Huffington Post reckons that Styles and his gang managed to rack up a bar bill in excess of £5000 on their jaunt out; this included 99 frozen margaritas, 20 Jagerbombs, 10 bottles of wine and three bottles of champagne. Hearty. Styles had actually started celebrating his birthday on Thursday night (January 31, 2013) with a dinner with two of his exes - Caroline Flack and Cara Delevingne - at swanky London restaurant La Bodega Negra. Styles' group, which included Nick Grimshaw and James Corden, then headed to the Groucho Club and onto Gerry's Bar, before finishing up at Base nightclub until 4am.

That wasn't it for the revelry either; on Saturday (February 2), his bandmate Niall Horan took him out on the lash with some more of his friends, the night culminating in the pop star receiving a dance at the hands of a stripper. We've got to hand it to Styles, he sure knows how to celebrate a birthday.
