Harry Styles apparently is seeing model Cara Delevingne. According to a source close to the model, the couple has been dating "for around two weeks." The source tells E! News, "Harry's been chasing Cara nonstop. He really likes her and has been saying that he wants to be exclusive with her."

The 21-year-old model, however, is not "sure" yet about their relationship, according to the source. Harry "says he wants them to be boyfriend and girlfriend. But right now, Cara is not sure what to do. She's a top girl and she's finding her feet right now. They are seeing each other though, casually, and are actually very cute together. Their friends think it could work out... He's really chasing her, but she's a really busy girl."

The source continues explaining that Cara will be busy in Los Angeles to take care of some business. "L.A. has gone crazy to sign her for acting jobs," the source says.

Speculations that the two are dating were fueled recently when the One Direction member was spotted with a woman who appeared to be Cara. The two reportedly went to watch a performance of Book of Mormon in London's West End. Harry was caught in camera talking to his phone while the blond woman beside him was sipping a drink.
