Our girl Brit won't be appearing live on Madonna's "Sticky & Sweet" tour, but she will be appearing via video - and it looks like she's about to shoot that video right now!

Britney Spears is currently at Kim Vo's B2V Hair Salon on Doheny, possibly prepping for the shoot says an X17 inside source...

There's been lots of speculation regarding where and when (and if!) Brit would be shooting said video for Madonna's latest tour, but our sources tell us it's happening today at a studio in Hollywood.

ALSO, we hear the crew for the shoot has been standing by all day being that Brit's call time was 7:30 this morning... guess there must've been a change in plans!

More to follow - stay tuned to X17 for the details!
