Britney Spears BSPEARSRPHILLIPPE051507_1.jpg

My day here at X17online just wouldn't be complete if I didn't post at least one shameless Britney teaser -- so here it is!

We got exclusive pix and video of Britney last night, partying at Les Deux with her cousin Alli and friend Jessica and maybe, just maybe she met up with a mystery man inside the club?

Stay tuned ...
