After spending more than a year away from the stage, the legendary Beyonce will kick off her comeback mini-tour tonight at Atlantic City's Revel Resort and Casino. VIDEO: Beyoncé Takes Us Behind The Scenes Of Her Comeback Show! 

Beyonce didn't make the trip to London to see her husband Jay-Z and friend Kanye West tear down the O2 Arena, but that's because she's been on lock down preparing for her comeback show. 

So, how did Beyonce get that slammin' body back so quick? Eight/nine hours in the gym rehearsing for her upcoming Memorial Day Weekend comeback tour, she reveals. "Discipline!" 

ET also said Bey lights up when you ask her about her baby girl, telling the entertainment news program Blue Ivy is her reason for it all. 

PEOPLE's World's Most Beautiful Woman recently spoke with the magazine about how she prepared for little Blue's birth, and how she's handling her body post-pregnancy. 

The new mother and People's Most Beautiful Woman revealed to the magazine that her body is bouncing back, adding her "waist came back too fast." 

The new mother landed the cover of People Magazine's Most Beautiful People Issue. The caption simply reads Beyonce: World's Most Beautiful Woman, and we think they couldn't have gotten it more right.  

According to a source at Look Magazine, the 30-year-old "Love On Top" singer wants to set a good example for her daughter, Blue Ivy Carter, so she's eating whatever she wants.
