'I've lost 60lbs!' Beyonce reveals she hit the treadmill and ate lettuce to shift post-pregnancy weight

Beyonce gave birth to daughter Blue Ivy nearly five months ago and the new mother has revealed how much weight she has lost.
During her second concert last night of her four-date stint at Revel Beach Ovation Hall in Atlantic City, the Single Ladies star told the audience about
her post-pregnancy regime.
'Y'all have no idea how hard I worked,' the 30-year-old told her fans. 'I had to lose 60 pounds. They had me on that treadmill. I ate lettuce!'

'Now tonight I'm gonna get chocolate wasted!' Beyonce exclaimed as reported by Us Weekly.

The starlet, who is married to rapper Jay-Z, wore a series of custom-made Ralph & Russo designs.
It's been nine months since Beyonce last performed for her adoring fans.
Taking to the stage in New Jersey last night for the first time since giving birth to daughter Blue Ivy, it appeared her time out for motherhood hasn't affected her stage presence.
Beyonce had a few famous people in the audience including First Lady Michelle Obama and her two daughters; Malia, 13, and Sasha, 10.
Also supporting her from the wings was her rapper husband Jay-Z, who recently returned from the London leg of his Watch The Thrones tour with Kanye West.

Under his Twitter name Mr Carter, he wrote: 'I'm gonna say this and then I'm gonna end mine. BEYONCE is the best performer in the world. Period.'
Speaking to the 5,500 fans at the Ovation Hall in the Revel, she said: 'I gotta say, it feels so good to be back home on stage.'
However, she didn't bring up her new life as motherhood too often, except for a fleeting glimpse of Beyonce cradling her daughter in a video montage on the screen behind her.
During the set, she performed a selection of her biggest hits, including Crazy In Love, Love On Top, Irresistible and If I Were A Boy.
She paid tribute to the late Whitney Houston with a cover of I Will Always Love You and closed the concert with Single Ladies (Put A Ring On It).
