Over the years, Matthew Perry's sobriety has been a hot topic in Hollywood. The 50-year-old actor has always been open about his struggles, which started pretty early in his career. During his time filming Friends, the actor reportedly faced problems with addiction, but luckily, he had a ton of support from not only his co-stars but also those working hard behind the cameras.\nAt Saturday night's Screen Actors Guild Awards, Friends co-creator Marta Kauffman opened up about her experience working with Perry.\n"We were certainly aware of some of it and we certainly had some conversations about it. [We were] protective and, hopefully, supportive," Kauffman told reporters from Us Weekly and other outlets.\nFriends was filmed for 10 years, from 1994 to 2004. During this time, Perry apparently checked into rehab twice — first in 1997, and once again in 2001.\nPerry never hid his struggles from his fans or the general public.\nIn a 2015 interview with The Hollywood Reporter, the Fools Rush In actor admitted that he's glad he's able to help others who are suffering from addiction.\n"I've had a lot of ups and downs in my life and a lot of wonderful accolades, but the best thing about me is that if an alcoholic comes up to me and says, ‘Will you help me stop drinking?’ I will say, ‘Yes. I know how to do that.'”\nMatthew Perry | IMDb\nPerry took his desire to help others one step further after completing his second round of rehab when he opened the Perry House — a sober living home that was actually run out of the actor's former home in Malibu.\nAlthough it's been over a decade since Friends came to an end, the cast still remains incredibly close and spends time together frequently. Jennifer Aniston joined Instagram back in 2019, and her first post was a selfie with her co-stars, captioned, "And now we’re Instagram FRIENDS too. HI INSTAGRAM 👋🏻".\nView this post on Instagram And now we’re Instagram FRIENDS too.

Today it’s just maybe," HBO Max CCO Kevin Reily said at the Television Critics’ Association’s winter press tour earlier this month, according to Deadline.
