One Direction's Harry Styles

Who is Harry Styles now dating?

So far this week it has been revealed that Harry is well endowed (thanks to his pal Ed Sheeran) and the One Direction singer (other band members include Zayn Malik, Liam Payne, Niall Horan and Louis Tomlinson) is now rumored to have his weekend planned with his rumored new girlfriend Cara Delevingne.

The sexy model has a birthday this weekend, the blonde beauty turns 20, and Harry may be helping with the party planning.

Will Harry perform at her birthday bash?

The hunky young singer has been asked if he would perform at the event to celebrate her 20th year, which Cara's sister Poppy is helping to organize.

A source told The Sun newspaper: ''As Harry and Cara have hit it off, they thought it would be nice to ask him if he'd sing to her. Whether it's a special rendition of Happy Birthday or something else is undecided. It all depends if Harry has the guts.

''Cara's a decent singer herself so she'd appreciate a tuneful serenade.''

The pair were last seen together on Saturday at Olympic VIP club Omega House in London's West End.

Harry took Cara home after the occasion in his Range Rover car.

Singer Ed Sheeran recently described Harry as ''packing heat''.

The 'Lego House' hitmaker was given a lift by Harry's band One Direction - made up of Harry, Zayn Malik, Liam Payne, Niall Horan and Louis Tomlinson - back to London after a gig, when he came upon the 18-year-old hunk with no clothes on and was impressed by the size of his manhood.

Ed said: ''I turned around and Harry was stripped off and completely naked, just sitting there laughing. Literally, I was looking out of the window, watching cars go past. I turn around, all the boys are kind of shocked, and there's just him laughing, completely naked.''
