Matthew Perry, best known for his role on hit US sitcom Friends, has died at the age of 54.
Law enforcement was called to the scene at 4pm local time for a ‘water rescue’.
It’s reported he drowned in a hot tub at his house in LA.
An investigation is ongoing but there's no sign of foul play.
Born in Massachusetts, Perry was raised in Ottawa, Canada and moved to LA to pursue an acting career at the age of 15 - joining the cast of Friends at the age of 24.
As the character Chandler Bing, Perry became known for his use of sarcastic one-liners.
He was nominated for five Emmy awards and one Golden Globe across his career.
The actor had previously shared his issues with addiction, including a near-death experience in 2019 after his colon burst as a result of opioid use.
In his recent memoir Friends, Lovers, and the Big Terrible Thing, he also described his struggle with addiction while on the hit sitcom.
He later set up Perry House, a centre in Malibu for men with drug addictions.
Actress Maggie Wheeler who played Janice in Friends said Perry brought “joy to many” and she's “blessed by every creative moment” they shared.
