Don’t worry guys, I couldn’t pick ANTM’s guest judge Matthew Rolston out of a line-up either.

I mean no offense to Rolston, but I’m not as familiar with him as other designer’s. In this episode of ANTM the model wannabe’s have to pose on rollercoasters. And who here HASN’T done that? You know how they snap your picture while you’re on a coaster, and you can pay to have it (DESTROYED)? Who among us hasn’t ever tried to pose beautifully as that flash went off, only to discover we look like we’re about to vomit? Don’t make me feel alone here!

Anyway, the photo shoot is where the gals look like they’re underwater. I wonder how many of them looked to Ariel of The Little Mermaid of ideas? (Seriously, what other famous mermaids ARE there?) I have pictures of the prep/behind-the-scenes for that shoot below. Check back later for the images of the actual photoshoot!
