New Britney Spears pictures have been released on her official site, showing the star and her dancers after they rehearsed a new number for her concerts.

The hot new number, whatever it might be, will be unveiled in Europe during the current leg of her Circus tour next month. What do you think it will be?

Here's Britney kicking it with her merry band of Circus helpers ...

If you ask us, as long as she gets the right city when she gives a shout-out, and goes home to Jason Trawick after the show, it can only be a success.
