Bertinelli, who found fame playing Barbara Cooper on One Day at a Time, and Van Halen were married when she was just 20 years old and stayed together until 2001 (via Today). Vhnd reports Wolfgang was named after the famous composer of the same name, Wolfgang Amadeus Mozart. And Van Halen's famous song "316" commemorates his birthday, March 16. Wolfgang claimed he had no idea he had famous parents at first. It wasn't until he started picking up CDs and saw pictures of his father that he realized his dad was actually a rock star (via iHeartRadio).

Bertinelli has said drugs and infidelity were part of the marriage — and ultimately confessed, "I got tired of, once again, hiding and thinking this is not the life I want for myself, for Wolfie, especially, and I don't want to keep treating Ed so badly" (via Today). She added, "But I think really what my sorrow was, that I wasn't giving my son the life I thought he deserved."

Later, when Bertinelli's son began playing bass with the band, she admitted she wasn't a huge fan of the idea. "He told me, 'You were working at this age, too.' He really gave me a good argument and I said, 'I don't want you to go, but I'm not going to stop you." There probably wasn't much Bertinelli could do to stop Wolfgang from performing on stage with his dad. According to iHeart Radio, he was playing drums by age 9, and could figure things out by ear on the keyboard. He then picked up guitar two years later.
