On the second night of Beyonce‘s four-night concert return at the Revel in Atlantic City, N.J., the R&B songbird was upstaged by none other than Michelle Obama, who was in attendance along with her teen daughters Sasha and Malia.

It’s no secret that Bey admires the First Lady and vice versa, but on Saturday night (May 26), Michelle received a round of applause from the sold-out crowd at Revel’s Ovation Hall, according to Press of Atlantic City. Although the Secret Service agents were reportedly guarding Michelle and the kids, concertgoers didn’t notice anything peculiar as they enjoyed the show.

According to Us Weekly, Michelle danced along to ‘Crazy in Love,’ while all three were mimicking Beyonce’s famous dance steps during her rendition of ‘Single Ladies (Put a Ring on It).’ “When Beyonce told the crowd to get up and jump, [Malia and Sasha] stood and started dancing and jumping,” said an eyewitness.

The First Lady wasn’t the only VIP guest attending Saturday’s concert. Oprah Winfrey’s BFF Gayle King, actress Maria Bello, Baltimore Ravens running back Ray Rice and New Jersey Gov. Chris Christie and his family were all in the house.

As we previously reported, Beyonce shined on her first night of her four-show residency at the Revel. For two hours, the 30-year-old songbird wowed audiences with her showmanship and looked fabulous in her post-baby appearance.

The Revel shows are Beyonce’s first concert performances in 2012 since giving birth to Blue Ivy in January. “Y’all don’t know how hard I had to work,” she told the crowd. “I had to lose 60 pounds. They had me on the treadmill, eating lettuce.”
