Keenan Cahill, an acting and singing enthusiast who looks much younger than his 15 years, just hit the internet version of the bigtime with his lipsync of Katy Perry's "Teenage Dream." He's been on several blogs, received big ups from Perez Hilton (who called him "Lil Katy Perry Lover") and even scored a tweet from Ms. Perry herself.

Keenan's emotive Katy Perry performance isn't his first taste of YouTube fame. Urlesque spotted him before he was big, but he first got noticed last year for his cover of a Jonas Brothers song. That led to a radio interview on the Stylz and Roman show in his hometown of Chicago, where he talked about how much he loves singing and lipsyncing, and revealed his aspirations of becoming an actor.

That was back when his whole channel had only scored 600,000 views, though. This new Katy Perry video has picked up 3 million in the space of a week. Now there's every indication that Keenan is poised to become a huge YouTube star or score a reality show ... seriously, someone get this kid on America's Got Talent!
