"I was watching porn every day - the real hardcore stuff. I was addicted," she told New. "At first, I started off on this website which was free, but then I was well into the hard stuff.
"I was fascinated. Especially when there was one girl and a load of blokes. I couldn't get my head around it! One's enough for me!"
Gibson also admitted that she cannot bear to be touched by fiancé Luke Sanwo after putting on two stone during her recuperation.
"I don't feel sexy at all," she stated. "When you don't feel sexy, it's the worst thing ever. I don't want him touching me. I can't think of anything worse."
Gibson proposed to her plumber partner in February after dating for just six months.
She recently vowed not to become dependant on alcohol and drugs again as she has "so much to lose now".
