Harry Styles wants the world to know that he's still single. 

On Monday, the One Direction member was spotted sitting front row at the Burberry fashion show in London, where his rumored girlfriend model Cara Delevingne was walking the runway. 

While waiting for the show to start, he was asked by a "MTV News" reporter if he was "looking forward to seeing [his] girl?"  The 19-year-old responded quickly, saying "She's not my girl!"  He even took a shot at the leading question adding, "I know what you're doing." 

Later, photos of Harry posing with British it-girl backstage after the show found their way onto Twitter. 

A source has also told "E! News" that the two have been dating exclusively for the past two weeks.
