You like myself maybe asking the question why, and/or WTF!? I personally think MTV is using her publicized train wreck of a life lately to promote themselves, I mean there really is nothing she could do wrong and hurt MTV or her own publicity. Let’s say for example…Britney shaves her head on stage, would you be surprised? Britney gets down with some lesbian action, would you be surprised? Britney lip-syncs some garbage music and displays her beer gut to the world, would you be surprised? AP states:

Instead, MTV Networks Music Group President Van Toffler said Wednesday, it’ll be something “fun and unexpected” on Sunday night’s show.
So what made Spears and MTV reunite one more time?
“MTV has long played an important role in my career. How can I not be there to kick off their 25th VMAs? I’m excited to open the entire show, to say hi to my fans and to be nominated,” Spears said in a statement.

Overall everything this broad does is gold and is the best marketing scheme ever, no planning, no chorography, no time/effort what so ever….Britney could squat on the stage and take a dump telling the world MTV sucks and that shit would get more ratings than presidents get votes.
