Harry Styles: Cara's not my girl

Harry Styles has denied romance with Cara Delevigne.

The One Direction singer seemingly brushed off reports he has been dating the English model, who is younger sister to fellow clotheshorse Poppy Delevingne.

The 19-year-old performer coyly revealed they were not in a relationship while supporting her at a catwalk event.

"She's not my girl! I know what you're doing," he told MTV News at Burberry's London Fashion Week presentation.

The teenage heartthrob may not be strictly exclusive with the blonde beauty but he certainly knows why she is easy on the eye.

Harry admitted that her striking peepers are what help her sweep people off their feet.

"It's probably them eyebrows, yeah, probably them," he smiled.

Harry was seen that day taking snaps with his pal Cara backstage, images which later surfaced on social networking websites.

He and top fashion star were first linked last year, but their relationship was brief. After they were spotted on a theatre date in London's West End recently there was speculation they'd rekindled things, with both reportedly keen to make it work this time around.

"They have been trying to go on some 'normal' dates. He really wants to get to know her properly without a lot of attention," an insider told British magazine Grazia.

Cara has previously been linked to Justin Bieber and has insisted gossip about her romantic life often get out of hand.

It seems she is enthralled by Harry though and hopes to take some time getting to know him before making things public.

"Cara wants to take things slowly. Harry thinks she is the most interesting and level-headed girl in the industry and it seems he doesn't want to let her go this time," the source explained.
