It takes a lot to upstage pop music’s hottest diva, but when you are first lady of the United States, you can pull it off.

Michelle Obama received a thunderous round of applause Saturday night from the crowd attending Beyonce’s second sold-out show at Revel’s Ovation Hall.

Obama visited as Beyonce plays four shows at Revel to help mark the megaresort’s grand opening this weekend. Beyonce returns to Revel for shows tonight and Monday.

These are Beyonce’s first shows since giving birth to her first child, daughter Blue Ivy, in January.

The Revel shows are Beyonce’s only announced performances for 2012, which might explain why Obama — and daughters Sasha and Malia — made the trip to Atlantic City.

Young kids in Obama’s group seemed to enjoy the show, at various points pumping their fists and moving along to the music.

While Secret Service agents were reportedly on-site, Beyonce fans didn’t notice anything different as they entered the venue and enjoyed the show.

The first lady is a fan of the pop singer. Last week, when asked during an interview who in the world she would like to trade places with, Obama said Beyonce, saying it seemed like singers had so much fun.

Meanwhile, Beyonce and her husband, rap mogul Jay-Z, are big supporters of President Barack Obama. Beyonce performed at Obama’s inaugural ball in 2009.

Before the concert, Beyonce fans were buzzing over rumors Obama would attend.

Kendall Robertson and Robert Lewis had traveled from Richmond, Va., to see Beyonce and were excited over the possibility of also seeing the first lady.

“We saw on TV that she might be here. I’d be here, too, if I were her,” Robertson said.

“Her husband should be here, too,” Lewis said.

“But he’s busy running the country,” Robertson concluded.

The first lady wasn’t the only celebrity attending Saturday’s show. New Jersey Gov. Chris Christie and his family also bought tickets for the performance. Before the show, the casino held a red-carpet entrance for a variety of VIPs attending the event, including actress Maria Bello, models Janeil Williams and Emily DiDonato, and Baltimore Ravens running back Ray Rice.

The Beyonce shows are among the hottest events in Atlantic City this summer, with Revel saying tickets for the first three shows sold out within a minute of going on sale, prompting the need for the fourth show.
