Harry Styles proposes to fan

Los Angeles - Harry Styles has asked a fan to marry him.

The One Direction heartthrob popped the question to a lucky supporter who was dressed as a bride at the Little Things hitmakers' gig in Philadelphia on Wednesday after he picked her out of the sell-out crowd and joked he didn't want her efforts to go to waste.

While the boy band were thanking the audience at the end of their gig, Harry said: "I heard there was a girl here in a wedding dress ... is there a girl here in a wedding dress? Now I feel bad letting this go to waste so what's your name? Preeya? Preeya ... will you marry me? There's been a plot twist! OK .. awesome."

The 20-year-old singer then joked that he and his new love were going to wait until everyone had sent them presents to celebrate their engagement before calling it off.

He added: "We'll take the engagement gifts and then we'll ... OK, awesome. I almost wore my wedding dress. It could've been awkward. But that's a different story."

Ladies man Harry has had several failed high-profile relationships with stars including Kendall Jenner, Caroline Flack and Taylor Swift.

Taylor appeared to make a dig at Harry - who she split from in January following a brier romance - at the Teen Choice Awards this past Sunday when she made a cheeky quip while introducing the Choice Actor in a Drama Movie category.

Speaking to the audience, the 24-year-old beauty said: "Oh, hey guys. You know we've had some amazing memories here together at the Teen Choice Awards, and so, I was excited when they asked me to come and present this award, because no one knows more about dramatic males than I do."
