To keep her concert lineup from growing stale, Britney Spears has announced plans to jazz up her Circus tour with the addition of a new song. The singer–who is currently in Denmark to work with producer and old friend, Max Martin–revealed that she’s going to introduce a new song into the mix.

The pop star told Entertainment Tonight, “We have a song called ‘Mannequin’ that we’re adding to the show, which I’m really, really excited about, so it should be interesting. We have to update [the show] or it gets really boring.”

In addition, Spears will be revamping some of her classics for when she continues the tour in the U.S. at Madison Square Garden in NYC on August 24. Brit-Brit will then hit up Las Vegas in September before jetting off to Australia in November. Well, I’ll be excited to see the pics. Brit’s looking damn good these days.
