What is the ben issue with michelle from celebrity big brother?

[HeartOfJewellz]

well im kinda confused because once when michelle gets a letter from her boyfriend he writes that don't worry about the ben issue and then coolio says you can have it. (u no what i mean) and then later on when they have a task on the music thing michelle's first draft of her rap has something to do with ben and her. so what is between them?
