The Keenan Cahill 50 Cent Down On Me lip-sync video is taking the net by storm. This 15-year-old is a YouTube sensation who has covered such songs by Katy Perry, Usher, Michael Jackson and more. 50 Cent teams up with the YouTube celebrity to take on Down On Me by Jeremih and I must say, it is pretty effing hilarious. How can you not love this little guy?

The video was premiered on Chelsea Lately on Monday November 8th, 2010 with 50 and the YouTube star showing off some pretty fierce synchronized dance moves in addition to Cahill’s fabulous lip-synching skills. The hip hop star even gave his big fat blingin’ necklace to Cahill to sport during one point of the video.

In addition to the premiere, Keenan was interviewed by Handler on her talk show and even brought on the charm by giving the blond “cougar” comedian his digits. Talk about a brave thing to do considering Handler is rumored to be linked to beefed up rapper 50 Cent. I’m thinking 50 wasn’t worried.

Cahill has racked up over 30 million hits for his YouTube lip synching hits “Teenage Dream” by Katy Perry and DJ Got Us Fallin’ In Love by Usher. Talk about unbelievable! We’ve posted a couple of our favorite videos of Cahill and his skills, including the Chelsea Lately video premiere below?
