Niall and Barbara leaving the 'X Factor' after party

Uh-oh, new romance rumor alert! The Internet is buzzing with the news that Niall Horan of One Direction might be dating Victoria’s Secret model Barbara Palvin (if that name sounds familiar it’s because she was linked to Justin Bieber just as he and Selena Gomez were breaking up the first time). Why the dating rumors? Niall and Barbara were spotted leaving an X Factor wrap party together in London Sunday night and witnesses said they were even holding hands while they waited for their car.
