Beyonce is definitely the hardest working woman in show business.  It was all evident this past Memorial Day weekend as Beyonce sold out the premiere of the Revel Resorts in Atlantic City.  Everyone from her husband Jay-Z, her bandmates Kelly Rowland, and Michelle Williams, First Lady Michelle Obama and Sasha and Malia, Queen Latifah, John Legend, Kevin Hart who also had a show in AC, Jennifer Hudson, and the list goes on, were all spotted at the show.  During a recent rehearsal Beyonce was photographed rehearsing and Ms. Tina Knowles can be seen in the background holding Blu.
