Watch Justin Bieber Perform 'One Less Lonely Girl' On MTV's 'It's On With Alexa Chung'

Is Justin Bieber the new Robert Pattinson? I mean, sure he's shorter, younger, smiles way more, seems 100,000 times more fun, pretty much OWNS Twitter, and he's far better at music. But, like R Pattz, Justin Bieber not only has impressive hair, but he's a TOTAL ladykiller. Girls twice, even three times Justin Bieber's age are like SCREAMING their makeup off for The Biebs.

Watch him perform "One Less Lonely Girl" from today's episode of It's On With Alexa Chung, and see why Justin Bieber is basically Robert Pattinson, minus the British accent and brooding.
