Has Justin Bieber found love?

Last week Justin Bieber revealed he'd be happy to date an older woman. As he's still just 16, that's probably a good thing, right?

But over the weekend, Justin was at the White House Correspondents dinner in Washington, and he met up with twenty nine year-old American model and actress, Kim Kardashian. Justin posted a photo of the two of them together and Tweeted, 'look, it's my girlfriend'. Was he joking? Apparently not, as Kim then Tweeted back that she now had Bieber fever.

Does this mean Justin is now unavailable? We were hoping Justin would stay single until at least after the Summertime Ball. Come on, Justin! It's only four weeks away!
