Britney Wants YOU for Some Ding Dang Dancin'!

Talk about getting your freak on: TMZ has learned that Britney Spears will be holding an open casting call this afternoon for dancers for her new video and upcoming tour. And by "open," Britney really means it -- anyone can show up at Millennium Dance Studio to audition from 5-9 PM.

We're told that Britney is supposed to be there, and that everyone who shows up will be put on tape so Brit can watch more of them later. Could the Next Great Federleezy be discovered today?

Of course, Spears was supposed to be at auditions last Thursday and Friday as well, and we all know how that turned out.
