The kid who first got noticed lip-synching to tracks and who then appeared with 50 Cent and DJ/producer David Guetta posted a new video on Sunday, this time with DJ Pauly D -- of Jersey Shore fame.
But unlike Cahill's previous celebrity videos, he and Pauly aren't in the same room but appear only through the magic of video.
The video was apparently more than a month in the making.
"For Christmas I Want @KeenanCahill To Do A YouTube Video Of My Track "Beat Dat Beat" ....... Oooh Yeahhhh," Pauly D posted to Twitter on Dec. 11.
The tweet got Cahill's attention.
On Jan 11, Cahill posted: "@DJPaulyD when are gunna make that vid together?"
"@KeenanCahill Im ready When You are My Dude !!! Let Do It !!!" came the response.
And the rest is now Internet history.
"When that beat hits you, you need to fight back."
