Brown — who worked with Perry on the sitcom "The Odd Couple" from 2015 to 2017 — mourned her costar's loss in a statement to Today that reads: "It was the honour of a lifetime to get to work with the comedic genius that was Matthew Perry. He was kind, loving, hilarious and just a sweetheart of a man."
She continued, "My heart breaks that we are speaking of him in past tense when his spirit while here was so playful and vibrant even in the midst of his struggles. The loss of Matty is a loss for the whole world. I weep for his family and for everyone else who loved him dearly. Rest well, friend."
Brown also paid her respects to Perry on Instagram, writing, "Our #OddCouple family suffered a great loss today. The entire entertainment world has. I am too sad about the news to say more than this: @mattyperry4 was a sweetheart who deserved more peace in this life. I am heartbroken to hear of his passing. And am sad for the great talent the world has lost because of it. 💔 54 is too young to go. We love you, Matty! #RIPMatthewPerry 💔."
