From Toya’s World:

According to one of Beyonce’s dancers Ashley Everett (via Twitter), Beyonce WILL be performing at this year’s MTV Video Music Awards on Sept 13th. I heard about this over the weekend and was waiting on official confirmation. I guess, maybe it is one of those ’surprise’ guest performances, the ones that don’t get any official confirmation until the last minute? Sort of like Britney Spears and the 2007 VMAs, although that had to be one of the worst kept secrets in musical history.
