When I was watching Heidi Montag's sad sack performance at the Miss Universe Pageant yesterday, I noticed something felt a bit familiar. Luckily "The Hills" cast member Kristen Cavallari helpfully pointed out the reason why.

"I was really impressed," the Hills star told Usmagazine.com at a Nylon magazine party in West Hollywood Monday night. "It reminded me of Britney Spears at the VMAs -- whatever year that was -- when she ripped off her suit and was, like, nude with sparkles. She kind of looked like that."

Spears stripped down to a sparkly nude suit at the 2000 MTV VMAs for her performance of "Oops, I Did It Again." Montag -- who has said she wants to have a similar career as the singer -- showed off a sequin bra and matching nude pants for "Body Language." (Source)

The reason why it probably reminded her of it is because Heidi's performance basically copied off of Britney's to a T. No really, click here to see it, it's practically the same thing. Well, except for the fact that Britney's outfit looks like it was professionally tailored by a costume designer and Heidi's looks like it came from the DEB shop, not to mention Britney could actually sing and dance back then, and Heidi can do neither of those things. So in that respect, I guess what Heidi really copied off of was Britney's sluggish, dead-eyed 2007 VMA performance. For shame, Heidi. For shame.
