Are you excited for Brit’s performance on the Billboard Music Awards on Sunday? Billboard.com gave us a sneak peek of of what to expect about it.

Britney’s Big Opener

Bracco tells Billboard that Spears, who will receive the Billboard Millennium Award, is slated to open the telecast with a “kick-ass medley” of her greatest hits. “It’s going to be her with a couple dozen dancers, plus costume changes, and she’s going to walk through her catalog,” he says. Don’t expect any star cameos, though. “When you have Britney, you don’t need anyone else,” says Bracco.
