During her nine-year (1975-1984) tenure as Barbara Cooper on TV's One Day at a Time, Valerie Bertinelli grew from a chubby, awkward 15-year-old with only a smattering of bit-part credits into a polished actress and bona fide sex symbol. When Bertinelli "married" her One Day co-star Boyd Gaines in a 1982 episode, the ratings went through the roof, while many a male viewer's heart sank. One year earlier, Bertinelli had been a bride for real; her marriage to rock star Eddie Van Halen was kept under wraps by the series' producers for fear of damaging the actress' "Little Miss Perfect" image. Bertinelli's son by Van Halen was named Wolfgang, as in Mozart. While still a One Day regular, Bertinelli made the first of many TV-movie starring appearances in 1979's Young Love, First Love; later small-screen projects -- most of them packaged by Bertinelli's own production company, Bertinelli Inc. -- included The Princess and the Cabbie (1981), I Was a Mail Order Bride (1982), Shattered Vows (1984), The Seduction of Gina (1984), Silent Witness (1985), and Pancho Barnes (1988). Conversely, her theatrical-feature credits are limited, but include C.H.O.M.P.S. (1979) and Ordinary Heroes (1985). In the years since One Day at a Time, Valerie Bertinelli has starred in the short-lived TV series, Sydney (1990) and Café Americain (1993).

At the beginning of the 2000s, she landed a recurring role on Touched By an Angel. In 2005 she filed for divorce from Eddie Van Halen, and a few years later she would be the star of yet another series, the TV Land sitcom Hot In Cleveland opposite Wendy Malick, Jane Leeves, and Betty White.
