Catherine Elizabeth "Cat" Deeley (born 23 October 1976) is a British disc jockey, television presenter and former fashion model. At 21, she co-hosted the children's series SMTV Live, alongside Anthony McPartlin and Declan Donnelly. She hosted Stars in their Eyes from 2004 until 2006, and beginning in 2006, hosts So You Think You Can Dance.
While attending Sutton Coldfield Grammar School for Girls, aged 14 Deeley entered a regional edition of a BBC competition for The Clothes Show, where she made it to the national finals. Spotted by an agent for Storm modeling agency, she was quickly signed as a model under her nickname of Cat to make it easier for clients to re-book her.

Aged 16 and having gained nine A-grade GCSEs, Storm tried to persuade her to leave school. But cautious Deeley continued her A-Level studies at Bishop Vesey's Grammar School Sixth Form, where she gained four A-levels.

Aged 18, Deeley became a full time fashion model, making her first television appearance in 1994 as a model on the television Series Kilroy.
