Brit's Dry Run Heats Up VMAs

TMZ can show you just ten quick seconds of Brit's rehearsal for tonight's "MTV Video Music Awards."



Brit's performance will feature acrobatics, magic, dancing, her trademark lipsynching -- and lord only knows what else -- and what weave?! This is a huge night for Britney -- she might be on her way to repairing her career -- or back on the train to Crazytown!

Either way, ya gotta love her!
