Alex Kingston is one of the stars for the latest series of BBC genealogy series, Who Do You Think You Are? The actress will be part of the new series also featuring Annie Lennox, Hugh Dennis, William Roache, Patrick Stewart and Samantha Womack to name a few.
Alex isn't the first Doctor Who related person to feature on the show. David Tennant appeared on the series back in 2006 and Freema Agyeman was also due to appear in a later series but never materialised for some reason. The series starts with Alex's episode on BBC1, Wednesday August 15th at 9pm.
