Catherine Deeley was born October 23rd, 1976, in Sutton Coldfield, Birmingham, England. The farthest thing from model material while growing up in England (or at least that's what she thought), Cat never had modeling on her mind and was more interested in hanging out with her younger brother Max and being the tomboy that she was.

Although she wasn't all too concerned with her looks and cared more about her grades, Cat participated in a regional BBC competition called The Clothes Show, at age 14. The fact that she didn't win was of no importance; she still had the looks to get her to the final rounds of the competition, and was spotted by an agent from Storm modeling agency.
