When the first lady turns 50, she gets a big party. For Michelle Obama, that meant inviting 500 friends and family to the White House in January 2014. Beyoncé performed a set of six hits, John Legend sang two versions of "Happy Birthday," and Stevie Wonder spontaneously grabbed a keyboard to perform a medley of tunes.
The star-studded guest list included Mary J. Blige, Jennifer Hudson, Samuel L. Jackson, Magic Johnson, Gayle King, Paul McCartney, Bill and Hillary Clinton, Gladys Knight, Michael Kors, Rachael Ray, Smokey Robinson, James Taylor, and Al Roker. But perhaps the sweetest part of the night was when then-President Barack Obama shared a tribute to his wife, recalling the first time they met.
