Katrina Amy Alexandria Alexis Infield was born and raised in Brighton, England. Her maternal grandmother is Jewish. She took the surname Price after her mother remarried following the split from her biological father when she was a child. Price has an older brother named Daniel and a younger half sister, Sophie Price. She also attended secondary school at Blatchington Mill Secondary School which she later revisited for a TV show called "With a Little Help from My Friends". At the age of six she was molested in a park near her home. Her decision to start modelling came after a friend suggested she have some professional photographs/movies done. The pictures were sent to a modelling agency in London, and to her surprise, the agency invited her into their studios for a photo shoot and to discuss a contract. She began appearing on 'Page 3' of the The Sun newspaper (topless modelling) It was at this time that she assumed the name "Jordan" because posing for Page 3 can be detrimental to future modelling work. The name Jordan was coined by someone in the office of her manager.
