One Direction's bedhead hottie, the delightfully disheveled Harry Styles, is one of the most eligible young men in pop music. Millions of Directioners would be willing to sacrifice an ovary (or at least a limb) in order to meet, much less date, him. But could Styles be off the market?

It looks like the 'What Makes You Beautiful' singer might be enjoying a fling with model Pixie Geldof, as he was photographed out and about with her in London last week. They make a fine pair, Styles and Geldof, since they have the same messy but fashionable coif.

Styles, 18, and Geldof, 21, were snapped leaving Groucho in the wee hours of Thursday morning (Sept. 13) last week. They reportedly left the party at the club but didn't stop the good times. According to The Daily Mail, the good-looking twosome left with other pals and went elsewhere to keep the party alive.

The exact nature of their relationship is unknown and it's quite possible that they may just be friends or having a good time with no strings attached. It's anyone's guess. But given that Styles is scorching hot and the most sought after hunk in teen pop, any young, hot model would be out of her mind not to try and bag or snag Harry. On the flip, Styles has his choice of pretty much any female on the planet, so he is probably best served remaining single and living it up!

Yeah, Harry is utterly swoon-worthy and he is apparently living while he's young, to borrow a phrase from 1D's first single off of 'Take Me Home.'
