Wolfgang Van Halen is the 17-year-old son of Jenny Craig spokesperson Valerie Bertinelli and ex-husband/Van Halen lead guitarist Eddie Van Halen.
Eddie went to rehab in 2007 and -- due to an undisclosed health crisis -- had to interrupt Van Halen's tour earlier this month. Valerie has lost over 40 lbs on Jenny Craig.
Proving the apple doesn't fall far from the tree, Wolfgang is ... currently the bassist for Van Halen.
