The Keeping Up with the Kardashians star told UK's Heat magazine: "I'm obsessed with guys with tiny ears, they turn me on."
Kim also opened about her love for make-up. The 29-year-old said: "When I don't have make-up on, everyone's like 'Whoa, you look 19!' But I'm a glamour girl - I love make-up, I love hair.
"I don't feel sexy unless I'm fully made up."
Kim added that she isn't ruling out getting plastic surgery. She said: "I've tried Botox, I felt it made my eyes more squinty and small - it was not a good experience for me.
"You have to grow old gracefully, I don't know if I will be saying that after kids – I may want a lift or something…"
Here she is getting Botox for "the first time" - ha!
