Keenan Cahill (March 20, 1995 – December 29, 2022) was an American YouTuber and Internet celebrity who gained fame in the early 2010s for his viral videos in which he lip synced to popular songs.

Guest artists on his channel[1][2] included Jennifer Aniston, 50 Cent, Flo Rida, Katy Perry, Tinie Tempah, Maroon 5, Cody Simpson, Jason Derulo, Big Time Rush, Glee, The Wanted, LMFAO, Drake Bell, Justin Bieber, Gym Class Heroes, Xuso Jones, WWE wrestler The Miz, and Pauly D. He released two EPs and over a dozen singles on iTunes.

[3] He was diagnosed at the age of one with Maroteaux–Lamy syndrome,[4] which in his case resulted in developing an appearance much like that of people with dwarfism; Cahill was 127 centimetres (50 in), with thickening of the dura, shortened trunk, crouched stance, restricted joint movement, and enlarged hands.

In April, he appeared with Brian Wilson and Cody Ross of the San Francisco Giants performing Taio Cruz's hit "Dynamite".

In the fall, he performed in a music video with The Oak Ridge Boys for their song "What'cha Gonna Do".
