"I spent a lot of time at school cutting my split ends. I know it's weird, but it was an addiction."
Stealing her sister's thunder by winning the Strawberry Shortcake Beauty Queen Pageant at only four years of age when she wasn't even an entrant, Millie has always enjoyed the spotlight and hopes to become a model.
"I've always wanted to do some sort of modeling, whether it is catwalk, facial or photographic modeling for magazines," says Millie.
Describing her personal style as pretty and classy, Millie has been an animal lover from a young age.
"I've grown up with all types of animals," Millie reveals.
"My Nana has a farm and I've had rabbits, cats, dogs, birds, fishes, chickens, horses and turtles as pets so consequently I feel very passionate about animal rights."
Admittedly caring very much about her outward appearance as well, Millie is hoping to learn to be more down-to-earth and become smarter from socialising with the Geeks.
"I just hope they teach me to care less about my looks and more about important things which can make me more intelligent," she says.
Disclosing her ideal partner as Jack Dawson from Titanic because "he is so romantic and treats his co-star as a princess", Millie hopes to one day meet her Prince Charming who will be "dressed nicely" and take her on a romantic date "under the stars".
In the meantime, Millie is happy filling her days working in the ladies section of the bras and intimate section of a department store.
She admits she will miss her family and friends the most while in the house.
"I am used to seeing my family and friends every day so it's going to be strange to think about them going out and partying without me. But I'm sure there will be so much going on in the house there won't be too much time to think about them."
