Kate Upton doesn't have a "dark side"

She said: "I always thought Marilyn was so beautiful and iconic, it was amazing to even be mentioned in the same sentence as her.

"But I feel like nowadays it's easy to be genuine and show your personality, whereas I don't think Marilyn had that opportunity. And clearly she had a dark side, and I don't have that."

The 'Other Woman' star began her modelling career aged just 15 and has never been afraid to stand up for herself, though she won't lose her composure.

She said: "My mum told me when I was younger that I could never raise my voice but I could always match a tone. I've kept that with me because, in fashion, there can be some heated moments. I'm never the one raising my tone, but I will match one."

In 2012, Kate stood up to photographer Terry Richardson after he uploaded an infamous video of her in a bikini doing the Cat Daddy dance as she thought he was "disrespectful" making public something they had shot for fun.

Speaking to Alexa Chung for Vogue magazine, she said: "Yes, I did [confront him]. I was like, 'That was disrespectful, you could have told me!' Now, obviously, it's fine."
