The 30 year-old singer claims it was all about hard work and lettuce. Beyoncé managed to lose 60 pounds by eating a whole lot of lettuce… and rehearsing for an extenuating show like the one she pulled off in Atlantic City for four consecutive nights.

Beyoncé said, “Y’all have no idea how hard I worked. I had to lose 60 pounds. They had me on that treadmill. I ate lettuce! Now, tonight, I’m gonna get chocolate wasted!”

The new mama is rocking an incredible figure. I’d dare to say she is in the best shape of her life less than six months after having a baby. That deserves a chocolate celebration!
