This Jade Cartwright was a Page 3 model from about 1999 to 2002. She also appeared in the usual "Lads' Mags" such as Loaded and starred in a one hour Playboy DVD as a "UK Cybergirl Video centerfold". A professional model, she still models for fashion and lifestyle magazines, and should not be confused with any other Jade Cartwrights, a quick Google search shows it's surprisingly, not an uncommon name :(
