A comic actress who also has excelled as steely, somewhat brittle women in dramas, Mimi Kennedy has been through the network TV wars, appearing in numerous short-lived series while building a reputation as a fine performer. She first won notice playing Jan in the Broadway musical "Grease" and by 1977 joined Debbie Allen and Ellen Foley as "Three Girls Three" (NBC), a critically-praised but short-lived program which was part variety, part sitcom. But it started Kennedy on the series path. She appeared in a supporting role in "Stockard Channing in Just Friends" (CBS, 1979) and was a regular on the short-lived variety program "The Big Show" (NBC, 1980). Kennedy went on to win praise as the career woman who hires Peter Cook to tidy up in the CBS series "The Two of Us" (1981-1982) and as mother to Chad Lowe's teen with tribulations "Spencer" (NBC, 1984-1985) She was married to Richard Libertini in "Family Man" (ABC, 1988) and was sister-in-law to Peter Onorati in "Joe's Life" (ABC, 1993).
