Answer by taking a quote from the following article:

Catherine Zeta-Jones, CBE (; born 25 September 1969) is a Welsh actress. Born and raised in Swansea, Zeta-Jones aspired to be an actress from a young age. As a child, she played roles in the West End productions of the musicals Annie and Bugsy Malone. She studied musical theatre at the Arts Educational Schools, London, and made her stage breakthrough with a leading role in a 1987 production of 42nd Street.

Zeta-Jones was born in Swansea, Wales, on 25 September 1969 to David Jones, the owner of a sweet factory, and his wife Patricia (nee Fair), a seamstress. Her father is Welsh and her mother is of Irish Catholic descent. She was named after her grandmothers, Zeta Jones and Catherine Fair. She has an older brother, David, and a younger brother, Lyndon, who worked as a sales representative before venturing into film production. Zeta-Jones was raised in the suburban area of Mumbles. Because Zeta-Jones was a hyperactive child, her mother sent her to the Hazel Johnson School of Dance when she was four years old. She was educated at the Dumbarton House School, a private school in Swansea. The family came from a modest background, but their fortunes improved when they won PS100,000 in a bingo competition, allowing them to pay for Zeta-Jones' dance and ballet lessons. Zeta-Jones participated in school stage shows from a young age and gained local media attention when her rendition of a Shirley Bassey song won a Junior Star Trail talent competition. As part of a dance troupe, she routinely took trips to London, where she auditioned for roles in the theatre. At the age of nine, she was selected to play one of the orphan girls in a West End production of the musical Annie, and in her early teens, she became a national tap-dancing champion. In 1981 she played the lead role of Annie in a Swansea production of the musical, which was staged at the Swansea Grand Theatre. Two years later, she played the lead role of Tallulah in a West End production of Bugsy Malone. When she was 15, Zeta-Jones dropped out of school without obtaining O-levels and decided to live in London to pursue a full-time acting career; she was also engaged to perform in a touring production of The Pajama Game. Describing her teenage years in London, Zeta-Jones said, "I would queue up for auditions and then change my costume or put on a different leotard and audition again. It might take me two tries, but I always got the job. I figured out what they wanted". She went on to attend the independent Arts Educational Schools in Chiswick, London, for a three-year course in musical theatre. In 1987, when she was 17 years old, Zeta-Jones was picked as the second understudy to the lead actress in a West End production of 42nd Street. During one of the performances, both the star and the first understudy were unavailable, and Zeta-Jones was asked to play the role of Peggy Sawyer--a chorus girl who becomes a star. The producer was impressed by her acting ability and allowed her to play the role for the next two years. Her next stage appearance was with the English National Opera at the London Coliseum in 1989 where she played Mae Jones in Kurt Weill's Street Scene. CANNOTANSWER
