This weekend's Global Citizen Festival was marked by star-studded performances, including a surprise appearance by perhaps its most famous performer, Beyonce.
Even more surprising? The wardrobe malfunction she suffered on stage!
The Queen Boo-Beys weren't advertised on the event's lineup, but they sure left a memorable impression as her dance moves jostled them loose.
Beyonce's white blouse, which didn't appear to be buttoned up and wouldn't qualify as workout attire even if it were, burst open to reveal her nude bra.
The 33-year-old seemed unconcerned with the mishap, continuing her live, Central Park performance without so much as missing a beat out there.
On hand was a 60,000 strong audience who had only been expecting Jay Z, who brought out his "Crazy In Love" collaborator, delighting the crowd.
And that was before she nearly went topless, too!
