She’s the First Lady, but Michelle Obama can still get down with the “Single Ladies.”

Obama and her daughters Sasha and Malia traveled to the new Revel Resorts casino in Atlantic City last night to attend a concert by the First Lady of pop, Beyonce.

The crowd cheered loudly as Obama made her way to her seat in a shiny green dress. Some took photos while others screamed her name. One fan yelled, “This is history!”

The singer’s four Atlantic City concerts this weekend are her first since giving birth in January to daughter Blue Ivy.
