"Be comfortable," Nicole urges Olivia. "I am not at all right now," Olivia replies.

"I'm so upset right now," Olivia says of the shoot. "I'm not a model, I'm like every other girl. I have insecurities. Everyone's staring at me, I'm in next to nothing, I'm beside Nicole, she's a full-blown model, she's gorgeous, thin. I'm feeling a little insecure right now in my own skin. Honestly I'm not even comfortable in like a bathing suit at a hotel pool. All eyes are on me and I feel like everyone is picking apart my flaws and I don't like that to be honest."

Olivia gets so uncomfortable at the thought of stripping down she actually walks off set, angering the photographer and crew!
