Kim recently whined on Twitter, "Why is it that the more I work out the hungrier I am!"

Well, when you burn calories, you get hungry!

Kim recently spoke out about the controversy over her Turkish Cosmopolitan cover:

"I just found out today that I am on the cover of Cosmopolitan Magazine in Turkey this month," she wrote on her website yesterday. "Cosmopolitan Magazine has a number of international editions all around the world that run in various territories, and when I did this shoot for the international covers I had no idea that Turkey was planning to run my story on their cover THIS month, considering Genocide Remembrance Day is this month. My Armenian heritage means a lot to me and I’ve been brought up to be incredibly proud of my family’s background and culture."
