She seems to feel that she was unfairly disadvantaged because Shayne was a "professional" actress. Chelsea says, "to me she was the falsest person here and for me to be up against her..." Matt Grant, the bachelor, comes to Shayne's defense. But despite Chelsea's allegations, an article in the Durango Herald shows us that Chelsea can do her own bit of acting.
"I think they're a better match," she nows says. "After watching the show, he's definitely not my type and not the man I thought he was. He's not athletically inclined, and I wouldn't want somebody to slow me down. When Shayne said she likes to shop, he thought that was cute. I didn't."
Sour grapes, anyone?
Then, to top it off, Wanstrath and many of her fellow contestants on the show, "thought Lamas, who is a professional actress, held an unfair advantage because of her experience in front of a camera." Wanstrath's mother adds, "we were suspicious of the whole thing - all these girls competing against a professional." (Read between the lines: "professional" means "super hot chick.")

So, folks, that is what we call rationalizing in psychology terms, or just putting on a front (or acting) in street language.
