Popular YouTube personality Keenan Cahill has died at the age of 27, according to reports.
Cahill found viral fame as a teenager in 2010 when videos of him lip-syncing to hit songs started gaining traction online.
Her first lip sync video was the Katy Perry hit Adolescent dream – from there, he developed a celebrity following, with celebrities such as Perry, Jennifer Aniston, 50 Cent, Flo Rida and Jason DeRulo appearing alongside him in his YouTube videos.
Chicago news station WGN9 first reported the news of Cahill’s death, saying a family spokesman had confirmed he had died Thursday at the age of 27.
The outlet said Cahill, born and raised in suburban Chicago, had become a “friend” of WGN over the years and described him as “one of the first internet sensations.”
Cahill was born with Maroteaux-Lamy syndrome and was only 127 cm tall. He received a bone marrow transplant in 1997 to try to stop the progression of the disease.
Cahill revealed his health issues continued in social media posts in the weeks leading up to his death, telling followers he was booked in for open-heart surgery on December 15.
“One week to open heart surgery… wish me luck, I love you,” she wrote, in a post that is now inundated with comments mourning her death.
“For those who ask for it. Dec 15th is the surgery date,” read what was to be her final Instagram post.
No cause of death has been released at this time.
In recent years, Cahill had turned his attention to DJing, releasing his latest track on YouTube three weeks ago.
