Perry, who played Chandler Bing on the iconic sitcom, was found unresponsive in his Los Angeles home on Saturday afternoon, per multiple outlets including TMZ and the LA Times. His death has not yet been confirmed by a representative or family member; an official cause of death has also not been provided.

Warner Bros. issued a statement about the star in response to the news. “We are devastated by the passing of our dear friend Matthew Perry,” it reads. “Matthew was an incredibly gifted actor and an indelible part of the Warner Bros. Television Group family. The impact of his comedic genius was felt around the world, and his legacy will live on in the hearts of so many. This is a heartbreaking day, and we send our love to his family, his loved ones, and all of his devoted fans.”

The actress—who played Chandler’s on-and-off girlfriend Janice Hosenstein throughout the sitcom’s 10-season run—posted a still from the series where she and Perry stood arm in arm.

“What a loss,” she wrote. “The world will miss you Mathew Perry. The joy you brought to so many in your too short lifetime will live on. I feel so very blessed by every creative moment we shared. ♥️”
