Harry Styles has one of the most talked about love lives in Hollywood. The latest rumour? A romance with British 'It' girl Cara Delevingne.

The 18-year-old heartthrob was spotted front row at the Burberry show during London Fashion Week yesterday, in which Cara, 20, happened to be modelling.

"Harry was smirking every time Cara came along the catwalk," an onlooker reported. "You could definitely tell there was chemistry there."

After the show, Harry was spotted giving Cara a cuddle backstage, before going in for — wait for it — a KISS!

"She looked amazing," Harry told ITN News. "She was great, she did a great job."

So what does Cara have to say of the rumours? "Oh, I don't know. I like to keep my private life private, that's all I'm going to say."

Do you think Harry and Cara could just be friends?
