Speaking in bed with JJ last night, the 29-year-old explained that her relationship on the outside world was never serious.
Asked about the reaction of her girlfriend to sleeping in bed with someone else, Corin said: "It doesn’t worry me.
"It may seem like I shouldn’t have done it [declared attraction to JJ] but while we had a relationship, it was more like friends."
Corin also revealed that her girlfriend wasn't keen on her entering the Big Brother house, adding: "I knew it was going to be an issue because she said a few comments."
The sales assistant has announced her attraction towards both Nathan and JJ during her time in the house.
