Katherine Heigl says being a child model was "brutal".

The 33-year-old actress - who raises three-year-old daughter Naleigh with husband Josh Kelley - began her career in showbusiness with a stint as a model for clients including US department stores Macy's and Sears but Katherine has admitted she hated the experience.

Speaking on TV show 'Anderson', she said: "Oh my god, it was brutal. You even understand it, even when you're nine, you're like, 'This is silly and lame' and they're like, 'No, no, it's adorable, do it.'"

Despite her background in The Fashion industry, Katherine admitted she is still insecure about her looks and was worried about shooting a shower scene for her new movie 'One For The Money'.

Katherine stars as bounty hunter Stephanie Plum in the film based on Janet Evanovich's novels and although she was concerned about her figure she explained she kept the scene in the movie because she loved it so much in the book

Speaking at the Paris premiere of the film, she said: "It's so uncomfortable. You are just never happy with the way you look.

"No matter how hard I tried or how little I ate that whole day hoping my stomach would stay flat, it doesn't matter."
