Heidi Montag channeled her inner-Britney on Sunday’s Miss Universe pageant, stripping down to a sparkly top and nude-colored pants for an energetic romp through her new single, “Body Language.”

Sure, the Hills star – and aspiring pop diva – didn’t appear to be actually singing live. But Montag worked the stage with abandon – and a fleet of dancers who stayed in sync to her moves.

“I am so excited to perform … at Miss Universe for my first ever live performance,” Montag told PEOPLE before the show. “This is such a miracle in life and I give thanks to God everyday for this once in a lifetime opportunity.”

Tell us what you think of her performance.
