The Beyoncé invasion is beginning. Pop’s fierce commander took to the battlefield on day 2 of her “Girl” music video shoot in Inglewood, Calif. Wearing a ... gold crown and waving a red flag emblazoned with “B,” the 29-year-old singer led an army of women on a post-apocalyptic set. The ladies posed against a ravaged car graffitied with “Revolution” with posters of their leader’s face behind them. The revolution will be televised.
