Beyoncé Knowles. Everyone knows her simply as Beyoncé, the multi-talented superstar wife of music-industry legend Jay Z. She’s also the glamorous and magnetic “Bey,” as President Barack Obama affectionately calls her. She’s held fundraisers for the President, performed at the White House, and cultivated a warm friendship with both Mr. and Mrs. Obama. Beyoncé often turns up at NBA basketball games, where she and her hubby can typically be seen in their courtside seats, soaking up the love of starstruck fans, broadcasters, and ballplayers alike. This past Sunday, as part of the Super Bowl halftime show, Beyoncé put on a performance that served as an ode to the 50th anniversary of the founding of the Black Panther Party.
