Mona in "Who's The Boss?''
Katherine Helmond may have played Alyssa Milano's grandma in the long-running Tony Danza sitcom "Who's The Boss?" but her character simply went by "Mona" — not "Grandma." Helmond also had a recurring role as Ray Romano's mother-in-law in "Everybody Loves Raymond.'' But the actress, also known for the TV series "Soap'' (1977-1981) and for Terry Gilliam movies such as "Time Bandits'' and "Brazil,'' has to really act in those roles: she has no children in real life.
