Although it rarely looked like she put on much weight during her pregnancy with Blue Ivy, Beyonce apparently had to shed quite a few pounds in order to prepare for her comeback concerts in Atlantic City this past weekend.

"Y'all have no idea how hard I worked!" the 30-year-old told fans at Revel Beach's Ovation Hall Saturday night. "I had to lose 60 pounds. They had me on that treadmill. I ate lettuce. Now tonight I'm gonna get chocolate wasted!"

She didn't look worse for the wear, though, displaying a sleek and toned body that certainly seemed primed for action.
