Harry Styles is dating Caroline Flack

One Direction's Harry Styles is dating 'The Xtra Factor' presenter Caroline Flack.

The 17-year-old pop star is reportedly smitten with the TV host – who is 15 years his senior – after the pair first shared a kiss at an 'X Factor' party last month and they cemented their relationship with a romantic dinner date at London's St Martin's Lane hotel on Tuesday (15.11.11).

A source told The Sun newspaper: "Caroline and Harry attended a showbiz bash, then went for a meal at the Asia De Cuba restaurant.

"They were clearly enjoying being together and didn't seem to care who saw them. Two other friends joined them while they were eating but it was clear they only had eyes for each other.

"Earlier in the evening, Caroline was in the lobby of the hotel on her phone waiting for Harry to arrive. Later they didn't try to hide the fact that they were jumping in a cab together either."

Last week, Harry's bandmate Louis Tomlinson revealed Harry had a girlfriend but refused to name Caroline, only saying: "Harry's found 'The One' now."

Harry has made no secret of his crush on Caroline, recently revealing he would love to take her on a date to McDonald's although he is worried about competition from her co-presenter Olly Murs.

He said: "Caroline is very nice. I do have a crush on her. If she liked me I'd love to take her out. How about McDonald's?

"Apparently she's seeing Olly Murs so I wouldn't want to share her with Olly."
