During her childhood, she moved around to various locales, including Harlington, Wembley, and Cardiff prior to settling in Gosport in 1994.

After departing school, she wished to join the British Army. After table and lap dancing for England's Sunday Sport newspaper, however, she fell into modeling. She is known for her appearances in Voluptuous and Score. Her work is primarily softcore in nature (masturbation films, solo dildo scenes, girl/girl).

After gaining a considerable amount of weight, she switched to the Score Group BBW/plumper magazine XL. She was voted Plumper of the Year 2005 and 2004 by readers of XL magazine.

Kerry is now posing for her new website "Officially Kerry Marie", which features new photo sets and videos. Kerry has posed for many professional photographers and many amateur photographers in the UK beginning with "Fiona Cooper," John Mason and James Elliot; and more recently with Flying Rabbits Video.
