Sarah Jessica Parker, Susan Sarandon and Lionel Richie were among the celebrities who investigated their ancestral history on the series, which ran for three seasons and was executive produced by former Friends star Kudrow.
Nbc executives decided to cancel Who Do You Think You Are? last May (12), but it has now been picked up by TLC.
A statement from Kudrow reads, "I've never stopped hearing about how much people love Who Do You Think You Are?, and I've always known that we've had more great stories to share. Tlc is a great home for the series, and we join our excited celebrity participants as we unearth some amazing background and surprising histories."
The new eight-part series will kick off in the U.S. on 23 July (13).
