My fantasy is, Chantelle is too "normal" to want to be a celeb. I imagine she will enjoy the moment, the limelight, the attention, and then when it has died down, happily drift back to her life before. Ok, it might be hard to put the genie back into the bottle. She was self-depricating, saying little-old-me, embarrassed, as if she really wanted only to have a BB experience, but not the responsibility of being a CBB contestant.
Anyway, its impossible to know, and to live through other people isn't healthy. She will do what she will do, regardless what we might dream for her.
She is certainly no Jade, who wanted it big and when it was offered on a plate, she scoffed and scoffed and hasn't stopped.
