'I'm not Brad Pitt, for God's sake...' The celebs who have spilled on their beauty and body hang-ups!

We all have insecurities but who would have thought that the rich and famous, beautiful and bold would do too? From Scarlett Johansson's thighs to Kate Upton’s breasts, these stars have proved there is no such thing as perfection as even they are self-conscious about their bodies...

She is considered to be one of the world's most beautiful women in the world, and with 326 million followers on Instagram her regular bikini selfies attract tens of thousands of likes. Kim may look flawless and boast an enviable hourglass figure but she had a problem with unwanted hairs which used to freak her out! Admitting to having the stray strands lasered off, she said: "My forehead had all these little baby hairs, and I would always break out because of them. I also lasered my neck because I had such a hairy neck. "I thought I looked better without the baby hairs, but now I miss them. "I think they look youthful! So ladies, you can always laser your hairline, but I miss mine."

The 90s icon was, and still is, one of the most famous and sought after supermodels in the world. But despite being famous for her good looks even someone like Kate Moss is insecure about her body. If Kate had one thing she could change about herself it’s her legs which she wishes were longer. She said: "I'd love to have longer legs. "So that's why I own lots of leggings: because they make my legs look longer."

She was named the Sexiest Woman Alive by Esquire in 2013, but even that wasn’t enough to convince the ‘Black Swan’ star that countless men desire her. Mila has always considered herself as a bit of an ugly duckling, and has therefore relied on her brains rather than her looks to get ahead. She said: "I appreciate the attention but I don’t think of myself as particularly attractive at all. I also don’t have that naturally ... sensuous way of behaving that some women have. "I have always worked hard and believed in myself as an actress in order to get where I am. I do have a pretty sharp sense of humor, though, and I think that has helped me."

He may have played Christian Grey, the fantasy of many women, in the '50 Shades' film franchise, but Jamie Dornan has never felt comfortable with his sex symbol status. Jamie has always thought of himself as "skinny and small", ever since he was at school. He said: "I think I am like anyone, I have massive hang-ups about my physical appearance... I was always fighting against stuff when I was a kid. I always felt skinny and small. Now, I'm 32... I have the same insecurities when I was a kid and when I see an image of myself, all I see is this skinny kid and I don't like it."

Mollie King - formerly of The Saturdays - just help but want a bigger butt, like her idol Beyoncé! Mollie - who is in a relationship with England cricket player Stuart Broad and previously dated model David Gandy - said: "I look in the mirror and see things I need to work on. I’d love to have curves like Beyoncé and a nice booty."

Scarlett Johansson is a dream date for men all over the globe, but she just doesn't like her legs, specifically her thighs. She said: "It's an okay body. I wouldn't say it's particularly remarkable, though. I don't like my thighs, my midsection."

Hamm earned a legion of female admirers thanks to his appearance in 'Mad Men', but he just can't understand what it is about him that women like about him as he thinks his looks are underwhelming. He said: "I don't know what it is, I'm not Brad Pitt, for God's sake!"

Even the ‘Naughty Girl’ can admit she’s not 100 per cent comfortable with her figure, which is one that most women would love to possess. In fact, Beyoncé actively avoids drawing attention to her ears. She said: "I wear big earrings because I don’t like my ears." Thanks to years of performing taking a toll on her feet, she wasn’t a fan of them either. She added: "After all the years dancing, they’re a little beat up."

The Sports Illustrated model should thank her bikini body for making her famous but instead wishes her ample assets were smaller. She said: "I wish I had smaller boobs every day of my life. "I love to wear spaghetti tops braless or go for the smallest bikini designs… Every single day, I'm like, 'Oh, man, it would be so much easier,' especially if people didn't constantly bring them up… If I could just take them off like they were clip-ons."

Kate Winslet has a curvaceous figure that is the envy of many, many women, and lusted after by many men. But the Oscar winner is not such a big fan of her bountiful butt. She said: "I don't know a single woman who doesn't stand up and check the tushie before she walks out the door. "I've decided I am going to start loving my backside, really just saying, 'yes'."
