She was married to actor Simon MacCorkindale at age 19, but the marriage ended in divorce. She then spent 13 years having "fun", but grew unhappy with her life. She met Neil Shackell, a computer marketing executive, through her cousin, Nigel Fullerton. The couple married shortly after meeting, and now live in the Cotswolds with James and their daughter Lucy.
Fullerton found that she had a "knack" for buying, doing up and then selling houses. She now has her own property company which buys and manages flats, mainly in London, and writes a series of columns on property investing. .
