Khloe Kardashian and her butt seen out and about in Hamptons

The reality star was spotted out and about on Tuesday in Southampton, New York. She's in town with her sister Kourtney to shoot their new reality show, Kourtney & Khloe Take the Hamptons. Now to the main purpose of this post...her butt. Did she surgically enhance it or she's just wearing butt pads...? Or she's always had butt like that and we never noticed it? It doesn't look naturally shaped though... what do you think?
