On Beyonce's Facebook page on a picture featuring her, Jay-Z, and the President, a woman named Donna Thompson commented the following:
Donna Thompson- How are you feeling Beyonce? Are you still not taking me seriously? Wait until you meet me in person in India. That is where and when the show will begin.
