Renesmee (Mackenzie Foy)

The only new addition to the Cullen family is nine-year old actress and model Mackenzie Foy, who was confirmed by Stephenie Meyer herself on the Twilight Facebook page as the one to play Renesmee, Bella and Edward's daughter. According to IMDb, her only other acting experiences have been appearances in two TV series, 'FlashForward' (2010) and 'Til Death' (2009).
