“The Hills” star Heidi Montag performed a lip synchronization with the song called “Body Language” at the 2009 Miss Universe Pageant on Sunday.

The 22-year-old reality TV star jumped onstage in a very revealing flesh-colored outfit, tossing her hair and thrusting her hips, while singing her brand new single.

Other guests at the pageant were rapper Flo Rida, disc jockey David Guetta and R&B singer Kelly Rowland.
