Minka Kelly was named Esquire magazine's sexiest woman alive back in 2010 and three years later she's just as stunning.

The 33-year-old actress is cautious of what she eats in order to maintain her slender figure.

"I try to be sensible and have egg whites and oatmeal for breakfast, a salad with protein for lunch, and fish and veggies at night," she told Self magazine in 2011. "But once in a while, I have that cheeseburger and fries."

While it may be hard to believe, The Butler actress also said she experiences days where she doesn't feel as assertive as others.

"There are days when I have less confidence than other days. When that happens, I try to treat myself the same way I would treat my best friend-meaning, I love my friends for who they are and don't focus on their flaws," she said. "So I try to do that for myself, too"

Kelly also told Access Hollywood in February that she works with a trainer three times a week in order to stay in shape. On the other days of the week, the actress said she participates in yoga and goes hiking.

"When I don't work out, I feel it in my body, I feel it mentally," she said. "I seem to have a better, more positive day when I get my endorphins going."
