Michelle Obama, Kids Hit Beyonce Show Singer making return to stage in Atlantic City By Newser Editors and Wire Services Posted May 27, 2012 9:56 AM CDT 17 comments Comments In this Friday, May 25, 2012 photo, Beyonce performs at Revel in Atlantic City, NJ. It is the first of four scheduled shows for Memorial Day weekend. (Robin Harper) (Newser) – Michelle Obama was with the single ladies this weekend, joining 5,500 fans at a Beyonce concert in Atlantic City. The first lady took daughters Sasha and Malia to Revel Resorts, where Beyonce performed two dozen songs last night. No sign of the president, but Gov. Chris Christie was among the sell-out crowd. Michelle Obama and the girls appeared excited throughout the concert, cheering Beyonce on. The daughters even sang along to the old school-sounding jam "Love on Top." The first lady got a roaring cheer that matched Beyonce's as she made her way to her seat in a shiny green dress. Some fans took photos while others screamed her name. One yelled, "This is history!" Beyonce opened the night with the upbeat "End of Time," and followed that with more up-tempo hits like "Crazy In Love," "Get Me Bodied," and "Party." The multiplatinum singer's Atlantic City concerts are her first since giving birth in January to daughter Blue Ivy. "Y'all don't know how hard I had to work," Beyonce told the crowd. "I had to lose 60 pounds. They had me on the treadmill, eating lettuce."
