Beyoncé performed live in concert last night at Atlantic City's Revel Beach Ovation Hall for the first time since giving birth to daughter Blue Ivy Carter back in January.
The singer was back to true diva form and lit up the stage in a custom-made Ralph & Russo fringed two-piece costume.
"Y'all have no idea how hard I worked!" the 30-year-old new mum told the crowd which included First Lady Michelle Obama and her daughters Malia, 13, and Sasha, 10.
"I had to lose 60 pounds. They had me on that treadmill. I ate lettuce!"
"Now tonight I'm gonna get chocolate wasted!" Beyoncé confessed to the crowd.
The figure-hugging midriff-baring ensemble featured over half a million Swarovski crystals and took more than four weeks to make.
