Valerie Bertinelli has had a hard time since ex-husband Eddie Van Halen's October death. The 60-year-old actress appeared on Monday's episode of the show and admitted that «it's been rough» and «very bittersweet» since the rocker's death. Bertinelli and Van Halen got married in 1981 and welcomed their now-29-year-old son, Wolfgang, in 1991.
