The "Goop" founder posted a tribute to Perry on Instagram detailing a time before they were famous when they spent a summer together. "I met Matthew Perry in 1993 at the Williamstown Theater Festival in Massachusetts. We were both there for most of the summer doing plays. He was so funny and so sweet and so much fun to be with. We drove out to swim in creeks, had beers in the local college bar, kissed in a field of long grass. It was a magical summer," she wrote. "He had shot the pilot of Friends but it had not aired yet. He was nervous, hoping his big break was just around the corner. It was. We stayed friends for a while until we drifted apart, but I was always happy to see him when I did. I am super sad today, as so many of us are. I hope Matthew is at peace at long last. I really do."
