Lisa Kudrow, Sarah Jessica Parker and Susan Sarandon explore their family histories in the U.S. reality series "Who Do You Think You Are?" NBC said Tuesday.

The program, which former "Friends" star Kudrow also executive produces, is set to premiere April 20.

In conjunction with Kudrow's production company Is or Isn't Entertainment and the U.K.'s Wall to Wall productions, the new show is an adaptation of the hit, award-winning British television documentary series of the same name.
