Jay-Z has decided to put his career on hold a bit for daughter Blue Ivy Carter, but for new mom Beyoncé, the show must go on.

"I'm back to work," the pop diva, 30, says in a video showing the process leading up to her return to the stage Memorial Day weekend at Revel resort in Atlantic City, N.J. "I'm back to business."
