Harry Styles cosies up to Laura Whitmore and Rita Ora, Cara Delevingne throws herself down some stairs

Harry Styles is Mr Party this week and after hanging out in the DJ booth at The Box on Sunday and partying with Billie JD Porter, he hit the town AGAIN last night for another big one.

<p>Harry Styles and Laura Whitmore cosied up at the War Child BRITs party.</p>

The One Direction star was a guest at the O2 and War Child BRIT Awards Concert in London last night where ex-girlfriend Cara Delevingne was also hanging out.

But it was her BFF Rita Ora and our new style crush Laura Whitmore who Harry was papped cosying up to at the intimate O2 Shepherd's Bush Empire gig.

Harry, who wore black jeans, a grey tee and a khaki jacket looked like he was having quite the night as he shared a drink with gorgeous Irish presenter Laura, who looked divine in tiny denim hotpants.

And he looked pretty pleased with himself to be snuggling up to popstar Rita Ora, who wore a bang-on-trend twee wide-legged trouser suit and fluro pink crop top.

Our spy inside the party told us: "Harry Styles turned up a bit late for the gig but joined right in, cosying up to Rita Ora."

<p>Harry's ex Cara partied with her wifey Rita at the Muse gig.</p>

Model Cara Delevingne,who reportedly dated Harry for a while last year, was clearly SO pleased about her ex Harry partying with all these other women that she took it upon herself to throw herself down some stairs later in the evening.

OK so it was probably unconnected but we found the thought funny anyway.

The London Fashion Week star left an all-night house party in the early hours and forgot to put one foot in front of the other so took a tumble down some steps.

Cara had been partying at the all-night bash with Harry and Rita.

Earlier the gang went from the BRIT Awards party to the Belvedere AnOther and Dazed & Confused parties where they hung out with will.i.am, Alexa Chung and Daisy Lowe.

According to our insider Harry and Rita left within minutes of each other *eyebrowraise* and Harry spent the evening chatting to Jamie Hince.
