Sunday night, "Hills" star Heidi Montag performed her new single "Body Langyage" at Miss Universe 2009 at the Bahamas.

Donning sparkly, nude-colored track pants with a tuxedo stripe and a black jacket, flanked by dancers, Heidi, who spent this past week practicing for the performance, removed the jacket to expose a nude-colored bra. It was a move that was similar to Britney Spears' 2000 VMA performance, during which she stripped down while singing "Oops! ... I Did It Again." And although Heidi smiled and seemed somewhat comfortable on the stage throughout her performance, she's not quite at Britney's level just yet. Source: www.mtv.com

Not sure why was she allowed or asked to perform at Miss Universe 2009?
