Kim Kardashian will always work hard to make sure her body is in its best shape.

The reality TV star is famed for her curvy and sexy figure, but says if she wasn't feeling comfortable with the way she looked, she would do something to change it.

"If I don't feel confident about my body, I'm not going to sit at home and feel sorry for myself and not to do something about it. It's all about taking action and not being lazy. So you do the work, whether it's fitness or whatever. It's all about getting up, motivating yourself and just doing it."

Kim also said her self confidence has improved with age and she is a lot more comfortable with her looks. "I didn't always have a lot of confidence - especially early on. As a teenager, and even in college, it was always my sisters that were the confident ones. But as I've got older, my confidence has definitely grown and I like the person I am today because of that. I get a lot of my confidence from my sisters," the 31-year-old beauty told Britain's Cosmopolitan."
