Harry Styles drove Cara Delevingne home in his Range Rover

Harry Styles is expected to sing at model Cara Delevingne's 20th birthday bash this weekend.

It seems the One Direction singer, 18, has made a good impression on Cara and he was snapped  giving her a lift home from the exclusive Olympic VIP club at Omega House in London's West End on Saturday.

'As Harry and Cara have hit it off, they thought it would be nice to ask him if he'd sing to her,' a source tells The Sun.

'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.'

Cara's older sister Poppy, 25 - who's also a successful model - is said to be helping her with the party planning.

Poppy has previously admitted to fancying Harry but it seems she's forgiven her sibling for getting close to the 1D star.

'I want to sit on Harry Styles' lap,' Poppy told Grazia last month.

'I have a total crush on
him. He walked past me at the Aquascutum show recently and I was
salivating. I like his curly hair and he looks like a little cherub.'
