At which 2013 event did Beyoncé perform the halftime show and reunite Destiny's Child?

Beyoncé performed at the Super Bowl XLVII halftime show and reunited Destiny's Child during the performance.

Super Bowl XLVII took place on February 3, 2013, at the Mercedes-Benz Superdome in New Orleans, Louisiana. Beyoncé headlined the halftime entertainment, performing songs from her solo catalog and staging a highly publicized reunion with Kelly Rowland and Michelle Williams.

The set included “Crazy in Love,” “Single Ladies (Put a Ring on It),” and “Halo.” Destiny’s Child joined Beyoncé for “Bootylicious,” “Independent Women Part I,” and “Single Ladies.” The appearance was notable because it was the group’s first major televised performance together in several years.

The game itself was played between the Baltimore Ravens and the San Francisco 49ers. The Ravens won 34–31. Beyoncé’s performance drew enormous attention and was followed by the announcement of her world tour, making the halftime show an important moment in her career.
