We all know the story: Britney Spears got divorced, shaved her head, beat a car with an umbrella, went to rehab for a little while, and generally acted in an unstable fashion in front of the paparazzi. Then, last year, she was supposed to put all of that behind her and reclaim her rightful crown as a pop princess by performing her new single, "Gimme More" at the MTV Video Music Awards.

So she opened the show--but her performance was more befitting a zombie stripper than a multi-platinum artist. Things continued to go downhill for a while, until her dad stepped in. After that, it was better extensions, visits with her kids and guest spots on How I Met Your Mother. It was good all around.

Now, after several months of relative stability, Britney may be ready for a comeback from her comeback. Along with VMA host Russell Brand, Spears is starring in a couple of promos for the VMAs. The videos are after the jump.
