"I gained 57 pounds when I was pregnant. I didn't have a lot of time to lose the weight, because I scheduled a show three months after I gave birth, which I would never do again," Knowles says. "I'm not a person that is naturally very thin. I am a person that has to work at keeping my body in shape," she goes on to say, adding that dance is what keeps her active.

"Not everyone is supposed to be the same. Be healthy and take care of yourself, but be happy with the beautiful things that make you, you."

VOGUE Michelle Obama April 2013

Michelle Obama stars on the cover of the April 2013 issue of American Vogue. This is the First Lady's second cover for the magazine. At the start of a second term, President Barack Obama and First Lady Michelle Obama talked to Jonathan Van Meter about their life as parents, their marriage, and their vision for America's families . :

First Lady Obama on making family her priority:

Our job is, first and foremost, to make sure our family is whole. You know, we have small kids; they're growing every day. But I think we were both pretty straightforward when we said, `Our No. 1 priority is making sure that our family is whole,'"

First Lady Obama on what she's learned from President Obama:

"Well, patience and calm I'm borrowing. Or trying to mirror. I've learned that from my husband, that sort of, you know, ability to not get too high or too low with changes and bumps in the road. To do more breathing in and just going with it. I'm learning that every day. And to the extent that I've made changes in my life, it's just sort of stepping back and seeing a change not as something to guard against but as a wonderful addition. . . that can make life fun and unexpected."

President Obama reveals what The FLOTUS has taught him:

"...What Michelle has done is to remind me every day of the virtues of order. "Being on time. Hanging up your clothes. Being intentional about planning time with your kids."

President Obama explains their differences:

"We're very different people, and some of that's temperamental, some of it is how we grew up. Michelle grew up in a model nuclear family: mom, dad, brother. I had this far-flung family -- father left at a very young age, a stepfather who ended up passing away as well. My mother was this wonderful spirit, and she was adventurous but not always very well organized."
