Former schoolmates of Grace have branded the housemate "a bully" and "a real bitch".
Despite her claims that she is "a nice person really", voices from her past disagree and have passed on their memories of her classmate's behaviour to The Mirror.
One acquaintance told the newspaper: "She was dense and flirted with the teachers to try to get the grades. And she was a real bitch. She seemed to have a problem with anyone prettier than her. And she bullied anyone she considered to be below her."
She also recounted the story of a school nativity play in which Grace insisted upon being the Angel Gabriel, even though someone had already been given the part. "She got her mum to complain to the teachers and in the end they had to have two Angel Gabriels because she couldn't handle being rejected," explained the classmate.
These sentiments have been shared by some of Grace's current housemates. Pete took offence at her mocking the new members of the group last night, whilst Nikki has dubbed her "vile" and "shallow".
