On Wednesday morning Kim Kardashian and daughter Nori arrived at sister Kourtney's baby shower at the Montage hotel in Beverly Hills, and we were surprised to see that the reality TV star covered up her prominent posterior! After flaunting her giant ass in all its naked glory on the latest cover of Paper Magazine, it's kinda odd that she's trying to keep it classy with a blazer, an when asked about her racy shoot, Kim declined to comment. C'mon girl, own it! Especially since it's really your only claim to fame...

Kim rocked a pair of booty-hugging spandex under her jacket, and Nori was all decked out in one of her new Balmain blazers, which were sent over by Olivier Rousteing last week. Wonder if Kim noticed that her little girl's foot had slipped out of her designer sandal? Hmm, probably not...

And is it just us, or did Khloe squeeze into this skintight white number just to remind us that Kim's not the only Kardashain with some serious junk in the trunk? Poor Kourtney -- this was supposed to be her big day, and yet again she's being one-upped by her little sisters...
