Actress Valerie Bertinelli and rock star Eddie Van Halen became parents over the weekend. Wolfgang Van Halen was born Saturday night at St. John's Hospital in Santa Monica, Calif., weighing in at 7 pounds, 13 ounces, said Maureen O'Connor, Van Halen's publicist. Van Halen was present throughout his wife's labor, she said. Wolfgang is the couple's first child. Bertinelli suffered a miscarriage in 1986, and the couple of 10 years has been trying to have a child ever since, O'Connor said. Bertinelli, 30, starred as the "kid sister" in the TV series "One Day At a Time," and Van Halen, 33, is lead guitarist for his band, Van Halen.
