The 24-year-old Quality Street heiress may live a life of luxury now, but her days at school were not all designer clothes and afternoon tea on Kings road.
'I was bullied to the point where I wouldn't go to school,’ she admitted to a UK magazine.
'I was skinny, had glasses and wore braces to realign my jaw.
'I had full-on yellow hair after a home dye job and had really bad acne all over my forehead.'
Speaking about her method of dealing with bullies, she explained:
'At school people used to call me names like 'Sparrow Legs' because I had such long, gangly limbs.
'But you have to rise above that. My mum always told me to be confident. I learnt a long time ago how to deal with playground bullying. It's a life lesson.’
‘Don't give them the time of day, they just want a reaction. I'm happy with my body and I know that's hard for a lot of girls to say,' she added.
The reality star also opened up about her two-year stint on Made in Chelsea, during which fellow cast member Victoria Baker was accused of bullying her, admitting:
'I'm not going to create a drama just to be part of it. Chelsea is a bubble and not a healthy one. It's that Gossip Girl environment and people just don't grow out of it.'
Engaged to 29-year-old Professor Green, who reportedly refused to appear on the show, they are said to be planning a lavish ceremony at Babington House in Somerset this September.
But it appears her fellow MIC stars won’t be invited.
'Nah, no Chelsea people,’ Green confirmed. ‘I don’t know many Chelsea people apart from Millie and her immediate circle, who aren’t in the TV show.'
