Catherine Zeta-Jones (pronounced /ˈziːtə/ "zeeta"; born September 25, 1969) is an Academy Award-winning Welsh actress based predominantly in the United States. She began her career on stage at an early age. After starring in a number of UK and US television films and small roles in films, she came to prominence with roles in Hollywood movies such as The Phantom, The Mask of Zorro, and Entrapment in the late 1990s. She won an Academy Award for Best Supporting Actress for portraying Velma Kelly in the 2002 film adaptation of Chicago, making her the first and only Welsh actress to win in that category. Zeta-Jones is married to Michael Douglas, with whom she shares a birthday. They have two children – Dylan (named after Dylan Thomas) and Carys.

Dawn French and Jennifer Saunders parodied Zeta-Jones as a vacuous über-celebrity named Catherine Spartacus-Zeta-Douglas-Jones on their show French & Saunders in the series Back With a Vengeance. Catherine Spartacus-Zeta-Douglas-Jones alternates between a strong Welsh accent and a strong American accent and uses Welsh-language phrases when she speaks.
