Valerie Bertinelli, who starred as One Day at a Time good girl Barbara Royer, told audiences watching

The Oprah Winfrey Show that infidelity and drugs ended her marriage to rocker Eddie Van Halen. But she also shouldered her half of the blame, admitting she cheated, too. The couple married in 1981 when Bertinelli was 20, and she claims she "destroyed" her body keeping up with the rock-star lifestyle. "It took me years after stopping the cocaine before I was able to enjoy a sunrise and enjoy the sound of birds," she said. Van Halen and Bertinelli separated in 2001, and their divorce became final in December. After losing 40 pounds, Bertinelli is currently the spokeswoman for Jenny Craig. She also has a new book out, Losing It: And Gaining My Life Back One Pound at a Time, which she plugged this morning following a One Day at a Time reunion of sorts on Today. What do you think? Does this news shatter her good girl image? - Adam Bryant Related: " See photos of Valerie Bertinelli " One Day Star Shares One Day in Her Life with Oprah
