Matthew Perry
The Gilmore Girls star remembered the witty card the "Friends" star included as well.
Keith Morrison married Perry's mother in 1981 and had known him since Perry was 12 years old.
Many fans were upset about the late Friends star's omission.
"I think he was the most talented of a very talented group of people..."
"I can imagine, from their side, they’re mourning someone who was still very close to them."
The Morning Show actor previously shared an emotional tribute to her former Friends co-star.
The Friends star was among those remembered at the Emmy Awards.
The Friends actor was found dead at his home in Los Angeles last year, at the age of 54.
"I never met the man, but owe him a debt of gratitude I can never repay — one for which I will never get to thank him."
The two actors knew each other well thanks to their work on ER and Friends, respectively.
