Asked if she, like many other women, is concerned about her weight and body image, Clinton replied, "Who isn't, really?"

However, the former first lady said she can count on her friends to help her deal with those insecurities.

"I have such a great group of friends -- friends that I have going back to literally kindergarten. Sometimes we have the same conversations we had in high school or college. I am still being kidded by my friends because I am hopeless when it comes to doing my own hair," she revealed.

The Democratic U.S. senator from New York said when she has a few moments to herself, she likes to catch up on her sleep, spend time outdoors with her husband, former President Bill Clinton, and even occasionally take in a movie by herself.

She also confided she likes organizing spaces in her home, adding, "I find cleaning closets and drawers to be extremely gratifying because you know there is a beginning, a middle and an end, unlike a lot of what I do which seems to be much more long term."
