Kate Upton was told to lose weight "all the time" when she began her modelling career.
The 24-year-old beauty is proud of her curves and refused to give in to the unrealistic pressure to change her shape.
She said: "At first I tried to diet to become their image, but eventually I realised that it wasn't realistic -- that this is just the shape of my body.
"So I had to block them out. I think that the people who are the loudest about wanting to change you are the people with the least amount of vision and creativity."
And the 'Other Woman' star couldn't understand the criticism of her figure because she was always working.
She told America's Glamour magazine: "Where I grew up, it was considered a great thing to have a curvy body to fill out a bathing suit. For that to be a negative was so confusing to me.
"And besides, when I started working, I was booked constantly, mostly for catalogue work. So when people were saying, 'Oh, she doesn't have the right look for a model', I thought, 'Then why am I working every single day?' "
The blonde beauty was inspired to become a model by her mother's reassurance when she was singled out by her classmates over her distinctive features.
She recalled: "Kids can be cruel, and they used to make fun of me for having long legs and bushy eyebrows. My mom would flip through magazines and say, 'Look, all these models have that too.' I decided I wanted to be a model."
