"I was probably sober two or three weeks maybe and I got a phone call from Steven Tyler, who I did not know," the "Parks and Recreation" alum continued. "He called me and said, 'I heard you're in recovery and I just wanted to say hey, you're going to do great.'"

But today because of that moment -- I am grateful and owe a thanks to them for my sobriety."
