On Saturday, January 18, 2014 Beyonce helped pal Michelle Obama, the first lady of the United States, celebrate her 50th birthday at the
White House in Washington. The “XO” singer, 32, who also performed at President Obama’s inaugural ball in 2009 and second inauguration in January 2013, joined a collection of performers at what is being called a White House “dance party” for the first lady’s big 5-0. The secret celebration hosted about 500 guests sprinkled with A-listers of the political and celebrity variety. Ledisi, a Grammy winner, opened the evening’s live performances, and Beyonce took over for about a 30-minute set accompanied by a full band, Us Weekly reported.
