Fans can soon see family histories of some of Hollywood's biggest celebs when NBC airs Who Do You Think You Are? this spring, Variety says. The show, based on the BBC original of the same name, will feature such stars as Lisa Kudrow, Sarah Jessica Parker and Susan Sarandon investigating their genealogy.

Kudrow will also be exec-producing the series via her company, Is or Isn't Entertainment, in partnership with U.K.'s Wall to Wall. Think will hit the airwaves in Chuck's slot starting Mon., April 20 (8 pm/ET), once the spy comedy has completed its spring episodes.

Will you tune in to get the backstories on celebs? Or is this TMI-in-the-making?
