Friends

The actor was found dead at his home in Los Angeles, law enforcement sources told US media.

Friends, which followed the fortunes of six young friends living in New York City, aired from 1994 until 2004.

Its final episode was watched by 52.5 million in the US, making it the most watched TV episode of the 2000s.

The LA Times and TMZ, which first reported that Perry had died, said the actor was found unresponsive in a hot tub at his house.

Tyler died peacefully at his home in Los Angeles on Sunday morning, a statement from his manager said.

"If you met him once you made a friend for life," it said. "[He] is survived by his wife, Jennifer Carno, the love of his life."

Tyler was diagnosed with advanced prostate cancer in 2018 which later spread to his bones.

"Wanting to help as many people as possible, he bravely shared his story and became a campaigner for those with a prostate to get a... blood test as early as 40 years old," his manager said.

In an interview with NBC's Today show, the 59-year-old revealed he was diagnosed in September 2018 after a routine physical examination.

The cancer has since spread to the actor's bones and he can no longer walk. He is undergoing chemotherapy.

"Eventually, you know, it's gonna probably get me," he told host Craig Melvin.

Speaking about his diagnosis, he said: "I was 56 years old at the time, and they screen for PSA, which is prostate-specific antigen.

Cox told TV host Jimmy Kimmel she remembered very little about the hit sitcom in which she played Monica for a decade.

"People love the show so much, I decided to binge watch Friends... it's really good!" she said via video link.

"I don't remember even being on the show, I have such a bad memory."

She added: "I remember obviously loving everybody there and having fun and I remember certain times of my life I was there, but I don't remember episodes."

According to The Hollywood Reporter, Jennifer Aniston, Lisa Kudrow, Courteney Cox, Matthew Perry, Matt LeBlanc and David Schwimmer, along with the sitcom’s creators, David Crane and Marta Kauffman, are discussing a possible reunion project for HBO Max.

The “unscripted reunion special” is said to be a long way from being a done deal.

The report comes as the loved show continues to celebrate it's 25th anniversary and amid ongoing hopes from fans that the cast will one day reprise their iconic characters.

The actor opened up in an interview with BBC Radio 2, admitting the filming blackout, after he was asked which episode was his least favourite.

"Oh my goodness. I think the answer is I don't remember three years of it. So none of those … somewhere between season three and six...a little bit of the time, I was a little out of it, yeah," he said.

For years, science has said that the limit is about 150.

Has Facebook - or other social networks, for that matter - managed to change anything? Can the Internet help us maintain more friendships?

An Oxford anthropologist and evolutionary psychologist who is one of the leading experts on those questions decided to take a look.

It's hoped all six besties - Rachel, Monica, Phoebe, Joey, Chandler and Ross - will reunite for a tribute to legendary comedy director James Burrows, who also helmed series such as Taxi,The Bob Newhart Show and Cheers.

The special will focus on Burrows' career.
