Music star Beyonce wowed thousands of people inside the Superdome and millions more on television in an electrifying performance at the NFL Super Bowl game in New Orleans - only moments before a power failure left half of the stadium in darkness.
The 31-year-old singer, who delivered a set list of her greatest hits, was also joined on stage by former Destiny's Child band members during the half-time show.
The lights went out in the Superdome soon after Beyonce's performance reached its climax and thousands of social media users jokingly commented that the singer's blistering dance routines were responsible for the blackout.
Players from Super Bowl finalists, the Baltimore Ravens and San Francisco 49ers had to wait for more than half an hour before they could resume play.
When play did eventually continue, the Baltimore Ravens defeated the San Francisco 49ers 34-31 to claim the coveted Super Bowl XLVII prize.
Before arguably sport's biggest contest began, the Sandy Hook Elementary School choir sang on stage with Jennifer Hudson.
Singer Hudson performed patriotic song "America the Beautiful" with the children.
