Beyonce Body After Birth: Singer Dropped 60 Pounds

Beyonce dropped a whopping 60 pounds after giving birth to Blue Ivy Carter -- that's according to the singer herself. Us Weekly reports that Bey told the crowds at her Memorial Day weekend show in Atlantic City -- her first time performing since giving birth on January 7 -- that she worked hard to get her post-baby body back.

"Y'all have no idea how hard I worked. I had to lose 60 pounds!" Beyonce reportedly belted out to the audience. "They had me on that treadmill -- I ate lettuce!"

The 30-year-old, 5-foot-7 Beyonce should serve as good inspiration to a fellow female star now in a similar position: Jessica Simpson. After giving birth to daughter Maxwell Drew on May 1, Simpson has declared she's ready to shed the pounds. "For me, I really want to do something that is a lifestyle, because in the past, I've been known to yo-yo diet," the 31-year-old "Fashion Star" judge told People magazine for its latest cover story.

It looks as if the pressure is on: Simpson reportedly inked a $3 million deal with Weight Watchers to slim down while serving as their spokesperson.
