YouTube Lip Syncer Keenan Cahill Jams to ‘Till the World Ends’

When YouTube lip-sync star Keenan Cahill arrives at the Atlantis Resort in the Bahamas, he's ready to lay down Britney Spears' 'Till the World Ends.' He quickly finds himself a VIP spot at Crush, the hotel's teen nightclub, and though he's alone on the dancefloor, he's got Britney at his side.

"What's up Keenan?" Spears tells the young vlogger, in a video message from the set of her own 'Till the World Ends' video shoot. "The only thing missing from this video set is you!"

Against the flashing club lights, Cahill sports a zip-up onepiece white suit and does his thing, mouthing along to the '...Baby One More Time' superstar's hot new dance hit. Per usual, this little guy -- who boasts 22 million views on his YouTube page -- is hilarious, especially when he zips his entire body into his outfit.

This is one of the first on-location shoots we've seen from the famed social media star, as he usually broadcasts his lip-sync numbers from his bedroom. To date, he's uploaded 96 videos, which span the music world with his version of everything from Katy Perry to Jay-Z, and of course, Britney.
