Teenage YouTube Breakout Keenan Cahill Gets an Assist From ‘Cougar’ Chelsea Handler

On Monday, Chelsea Handler welcomed as her Chelsea Lately guest 15-year-old YouTube sensation Keenan Cahill. The Chicago teen, who suffers from Maroteaux-Lamy Syndrome, has exploded with his lip-synched versions of various pop hits.

It certainly pays to have fans like Handler, whom Cahill hilariously referred to as a “cougar” during his E! appearance. As part of his LA visit, the head-bobbing cover artist got to work with rapper (and rumored CL boyfriend) 50 Cent, who drops in starting at the 1:20 mark to help with Cahill’s latest redo, “Down On Me.”

Check it out:

There is no one hotter in the Hollywood entertainment firmament right now than Handler. It’s a Chelsea Lately world, and we’re all just inhaling the vodka fumes. The hostess-with-the-coast-est also gifted Cahill with a new FlipCam.
