Cat Deeley, full name Catherine Elizabeth Deeley, is a British television presenter born in Sutton Coldfield, Birmingham, England on 23 October 1976.

After achieving nine A grade GCSEs and four A-levels at school, Deeley became a full time model with the agency Storm, who also have the likes of Kate Moss on their books. It was at this stage she shortened her first name to Cat, apparently because there were too many Catherines on the agency's roster. Deeley left modelling after two years and became an MTV UK presenter in 1997. A year later she became co-host with Ant and Dec on the Saturday morning children's show SM:TV, which she presented until 2002. She continued to present spin-off music show CD:UK until 5 March, 2005.

Other programmes she has hosted include Fame Academy, The Brit Awards 2004 and Stars in Their Eyes, as well as a weekly show on London's Capital FM and becoming patron of Great Ormond Street Hospital.

Renowned as one of the most beautiful women in the public eye in Britain, Cat has been a shoe-in to appear in 'sexiest women' lists and the like for several years, and has posed for countless photo-shoots in men's and women's magazines. Once, in 1999, perhaps not fully appreciating the passions she was stirring up, she offered her most devoted fans the ultimate ray of hope by casually musing in an interview that she would like to appear in a Playboy photo-shoot one day. When, in a separate FHM interview, she was asked to confirm in the plainest terms that she would pose completely nude for a photo-shoot if offered a million pounds, she replied unequivocally in the affirmative. To date, however, she has only occasionally whetted appetites in that kind of direction - once inadvertently, when the strap of her dress slipped during an interview to reveal one of her breasts, and the ever-eager photographers nearby were quick enough to capture the image. In her more planned forays before the camera, the furthest she has gone so far is a cheeky topless shot with her back to the camera. She has also appeared on television in a similar pose, addressing the camera while being massaged in Morocco for the travel show "Wish You Were Here?".

Cat once commented that the television personality she found most annoying was Vanessa Feltz, because she was heard talking about her private life too often.
