Valerie Bertinelli has been touched by an angel. The Hot in Cleveland star, 54, appeared on TLC’s Who Do You Think You Are? (airing Wednesday, Aug. 13 at 9 p.m. ET) to learn more about her lineage. 

Bertinelli is mom to son Wolfgang, 23, with ex-husband Eddie Van Halen, and is currently married to financial planner Tom Vitale. 

In the clip, researchers from Ancestry.com uncovered that Bertinelli’s great-grandmother had her grandmother out of wedlock, marrying her great-grandfather two years later. After they were married, Bertinelli’s great-grandparents welcomed her great-uncle. 

The Ancestry.com specialist gave potential reasons behind the delayed marriage, such as cost and dowry concerns, and then dropped an emotional bomb on the TV star.
