Khloe Kardashian is not like her sisters Kim and Kourtney.

 For starters, she's doesn't have the same body shape, she's married and she has fertility struggles -- but those differences have made her a strong person."I'm confident in who I am. I've always known that I'm not Kim and I'm not Kourtney -- I've always been OK with that," the 28-year-old reality star tells the June issue of Cosmopolitan U.K. about her body image. "I probably thought I was prettier before I entered the spotlight because being compared to somebody else every day does sort of beat up your spirit and soul. But it's made me stronger. I've gained another level of confidence.""I just wanted to be, 'Hey, let's have a baby,' and we would just have one. Kourtney did. And I wish that was the way for me," the "Keeping Up With the Kardashians" star admits. "But it won't be. I'll have to take hormones. I do want to have a baby, but I don't feel the urgency to have one this very moment."
