After sticking to a strict diet to lose baby weight following the January birth of Blue Ivy, singer Beyonce is planning to indulge.

“Y’all have no idea how hard I worked!” the new mom told fans during her concert at Revel Beach’s Ovation Hall in Atlantic City on Saturday night, via the Associated Press. “I had to lose 60 pounds. They had me on that treadmill. I ate lettuce!”

“Now tonight I’m gonna get chocolate wasted!” Beyonce exclaimed.

Beyonce’s treadmill confession surely pleased concertgoer First Lady Michelle Obama (who has partnered with the singer in the past to inspire kids to exercise with her “Let’s Move!” campaign).

The First Lady enjoyed the concert with daughters Sasha and Malia, who happily danced in their seats, reports Us Weekly.

“They sat up in a private balcony with Gayle King,” according to Us Weekly. “When Beyonce told the crowd to get up and jump, [Malia and Sasha] stood and started dancing and jumping. They were shouting when Beyonce asked, ‘Do girls run the world?’

“Together, all three of them did the ‘Single Ladies’ dance moves,” a concertgoer told Us Weekly..
