If you thought Beyonce ever took a day off from being her fierce, glam self, then you clearly don't know Beyonce. The '4' singer revealed to PEOPLE (via MTV) that she stayed fly right up until -- and even during -- the birth of her beautiful baby girl, Blue Ivy. There's a reason she's the World's Most Beautiful Woman!

Bey admits that she didn't feel like her bey-utiful self in the hospital when Blue Ivy was born. "I didn't feel that I looked beautiful during birth -- but who does?" she said. "After being pumped with all those fluids and gaining so much weight, with my swollen lips and cheeks, I barely recognized myself." Aww, Bey! Don't worry too much, though, because she took matters into her own hands -- and feet!

"I tried my best to roller-set my hair and I wore my [lip] gloss when I arrived at the hospital," Beyonce said. She also proved just what a determined lady she is right up to the delivery of the world's most famous baby. "I committed to the end and wore my kitten heels. It makes me laugh thinking about it," she said. "But after many hours of labor, I didn't care how I looked. It was all about the miracle that God gave me -- the opportunity to deliver a human being."

As for her bangin' post-baby bod, Beyonce admits that it hasn't been easy, but that she did get a little lucky with how quickly she's bounced back. "I'm proud that my waist came back so fast," she said. "I had to get my tone back. I'm definitely softer, but I feel my body bouncing back. Whatever was tight and muscular, like my legs, I'm seeing it come back. You just have to work at it."
