Valerie Bertinelli and former husband Eddie Van Halen in 2001.

Valerie Bertinelli says despite her girl-next-door image, her marriage to Eddie Van Halen was hurt by infidelity and drug use — by her, too.

"I wasn't an angel, either. I cheated, too," Bertinelli, 47, said on "The Oprah Winfrey Show" broadcast Monday. "He claims to this day that I cheated first, but I don't know. I don't know about the timing."

Bertinelli, who starred in the long-running sitcom "One Day at a Time," married Van Halen in 1981 when she was 20. She said she was "destroying my body," trying to keep up with a rock-star lifestyle on the weekends and weeks off from taping her TV show.

The couple separated in 2001. Their divorce became final in December. They have a son, Wolfgang, who's now 16 and touring as bassist with the band Van Halen.
