Over the weekend, Beyonce Knowles put on her first show since welcoming daughter Blue Ivy back in January.
Held at Revel Resorts in Atlantic City, the super star looked absolutely amazing on stage and sounded great.
So, who was singing along in the crowd during her gig? The First Lady, Michelle Obama, and daughters Sasha and Malia!
At one point, Bey told the audience how hard she had to work to prepare for this:
''Y'all don't know how hard I had to work. I had to lose 60 pounds. They had me on the treadmill, eating lettuce.''
Some of the songs on her set list included Love On Top, Run The World (Girls), Naughty Boy, Crazy In Love, and Single Ladies.
Watch her incredible performance of End Of Time, below!
