He's known for his penchant for older women after having romanced the likes of Caroline Flack and DJ Lucy Horobin in the past.

But it would seem Harry Styles has made the decision to find a girl more his own age if his latest squeeze is anything to go by.

The 18-year-old singer caused a stir when he was spotted leaving the exclusive Olympic VIP club at Omega House in London's West End with Burberry model Cara Delevingne in tow.

Leaving the nightspot in his Range Rover together, the One Direction hunk has reportedly been texting the 19-year-old beauty ever since they first met earlier this summer during a night out at Mayfair club Le Baron.

A source told The Sun: 'Lots of people saw them leaving together but they didn’t care. They only had eyes for each other.'

But in romancing Cara, it could be that Harry has sparked a spot of sibling rivalry.

The model's elder sister, Poppy Delevingne, has previously admitted to having a crush on the curly-haired cutie.

She told Grazia magazine: 'I want to sit on Harry Styles’ lap.

'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.'

Harry caused controversy when he dated Xtra Factor presenter Caroline Flack - who, at 32, was 15 years his senior at the time - earlier this year.

It was then revealed he had romanced married DJ Lucy Horobin, who is also 32.

But in recent months, the singer's penchant for older women seems to have waned somewhat, with him linked to Made In Chelsea beauty Caggie Dunlop, 23, The Inbetweeners bombshell Emily Atack, 22, and US model Emma Ostilly, 18.
