Harry Styles looked like he was feeling the effects of his three day birthday bender as he arrived at a mate's house with a mystery lady over the weekend.

The One Direction star needed the steadying hand of one of his security team as he got out of his car looking a little worse for wear.

Well, we'd be a bit wobbly if we'd racked up bar bills in excess of £5000.

In one bar alone, the singer and his mates downed 99 Frozen Margaritas, 20 Jägerbombs, 10 bottles of wine and three ­bottles of champagne.

Bleurgh.

Helping Harry drink the bars of London dry were 39 of his nearest and dearest including his showbiz chums Nick Grimshaw and Pixie Geldof.

The 19-year-old star kicked off the celebrations on Thursday night with a night on the lash with not one, but two ex girlfriends in the shape of Caroline Flack and Cara Delevingne at London's La Bodega Negra restaurant.

The group - which also included James Corden and Grimmy - later headed to the Groucho Club in Soho, then onto Gerry's Bar before finishing the night at the Base nightclub where they partied until 4am.

Then on Saturday, Harry was back on it with his 1D bandmate Niall Horan in tow who watched on as an embarrassed Hazza received a lapdance from a stripper, organised by his friends.

The birthday boy finally called it a night at 4am on Sunday morning and he was spotted leaving a house party with the same blonde he arrived with.

Phew. That boy sure has stamina. We, on the other hand, are exhausted just reading about it.
