Out to celebrate his birthday, Harry Styles partied at The Alibi Club in London, England early Saturday (February 2).

Accompanied by a gaggle of pals, the One Direction singer donned a blue-and-white sprinted shirt as he posed for pictures with a few ladies in a limo.

Appearing somewhat unsteady on his feet at times, the 19-year-old hung out at the posh hotspot until 3 am, before continuing the festivities at a nearby home.

Among those on hand for the big bash were Styles’ friends Nick Grimshaw, Miquita Oliver, and Pixie Geldof.
