In an interview with the Sun, Kate said she thought she was no better looking than the average woman and admitted she does not have 'perfect boobs'.
The 36-year-old said that it would be great if when she stripped off for movie roles her imperfect body empowered other women!
"I look like the people that walk down the street," she told the paper. "I don't have perfect boobs, I don't have zero cellulite - of course I don't - and I'm curvy. If that is something that makes women feel empowered in any way, that's great."
The actress then went on to add that this is the reason - 'on a deeper, subconscious level' why she has allowed herself to be 'so naked on screen.'
She also admits that she is now much less self-conscious about her body than she used to be:
"I remember being 21 and imagining that at 36 my t**s would be around my knees and I would have bad hair and terrible teeth. When you are younger, somehow being in your later thirties just seems really old. But I feel stronger, fitter and more comfortable in my own skin now than I have ever done."
Kate - who is mum to Mia, 11, from her marriage to film director Jim Threapleton, and Joe, eight, from her marriage to Sam Mendes - says that it is important for mums to keep a sense of who they are once they've had kids:
"There is something about hanging on to your sense of self as a woman in spite of having children and in spite of going through a lot of fairly big-deal things in my own personal life."
Admitting that her life has at times been tough, she said that she thinks she has 'emerged from some of those times feeling genuinely good and well and strong and together and with my children.'
The hard-working mum is currently filming her latest movie, Labor Day in which she plays a depressed single parent.
What do you think of Kate's comments?
Would you like to see more 'normal' women like her on screen, or do you think she is actually just as Hollywood perfect as the rest of them?
