Give yourself a gold star if you guessed that this behind is Kim Kardashian's. She tweeted the picture over the weekend and said:
Ummm in a fitting w @MonicaRoseStyle I think my butt looks too big in these jeans
Yes, clearly it's those leather jeans -- and not genetics -- that are making Kim's behind look big. I bet if she threw on a pair of denim, you'd mistake her for Jessica Alba from behind.
"Is that Jessica Alba?" you'd say.
