Alice Star Linda Lavin Mourns Death of TV Son Philip McKeon: 'He Taught Me How to Be a Good Mom'

Alice actress Linda Lavin is mourning the death of her former costar, Philip McKeon.

In a statement to PEOPLE, Lavin, 83, reflected on the “deep” connection she shared with Philip on the set of Alice, remembering him as a “wondrous boy.”

“Philip was the endearing, loving boy, always willing and eager to connect with others,” she said. “Although we were performing a show, the dynamic of creating that relationship made our connection very real and deep. He taught me how to be a good mom, just by being the wondrous boy he was.”

The hit 1970s comedy starred Lavin as a widowed mother and aspiring actress working as a waitress in Phoenix while raising her preteen son, played by Philip. Alice ran for nine seasons from 1976-1985.
