50 Cent, Keenan Cahill Team Up For 'Down On Me' Duo Lip-Sync (VIDEO)

50 AND KEENAN

Keenan Cahill, the YouTube phenom who got over 15 million views on his lip-sync of Katy Perry's "Teenage Dream," has a new video making its way around the internet. This time, he's lip-syncing "Down On Me," the Jeremih single featuring 50 Cent. Cahill, the adorably earnest Chicago youngster, mouths Jeremih's lines, and then a special guest drops in for 50's verse: 50 himself. The multi-platinum rapper has to bend down to fit in the frame with the glasses-wearing 15-year-old. But the two dance around young Keenan's room, and 50 even drops some ice on his neck toward the end of the video. It's such a cute video that it almost makes us glad Curtis didn't retire three years ago like he said he would.
