As predicted, Beyoncé performed at Michelle Obama's 50th birthday party on Saturday, Jan. 18.
The singer, 32, posted a series of pictures from the intimate gathering via her Tumblr blog the next day. They show the "Partition" singer posing in a sequined gold mini-dress and nude heels, as well as petting one of the First Family's dogs. Beyoncé has a longstanding relationship with the Obama family. She serenaded the political power couple during the president's first inaugural ball in 2009, and she performed at his swearing-in ceremony in 2013. First Daughters Sasha and Malia are also big fans.
In addition to Beyoncé, John Legend also performed at the White House party. Famous attendees includied Mary J. Blige, Jennifer Hudson, Samuel L. Jackson, Magic Johnson, Gayle King, Gladys Knight, Michael Kors, Rachael Ray, Smokey Robinson, Al Roker, Sheryl Sandberg and Stevie Wonder.
