B, People's 2012 Most Beautiful Woman, opened up to the magazine about her labor preparations. And it's no surprise that she lived up to her title -- B tells People:
"I did have a fresh eyebrow wax," PEOPLE's 2012 Most Beautiful Woman says with a laugh.
"I got my nails done, I got my feet done, had my hair done, and I had my little lip gloss."
"I didn't feel that I looked beautiful during birth, but who does? After being pumped with all those fluids and gaining so much weight ... I barely recognized myself," she explains.
"But after many hours of labor, I could care less about anything but my child. I didn't care how I looked."
The focus, she adds, was shifted to "the miracle" that she and husband Jay-Z welcomed into the world.
She also talks about how she took off the 50 lbs she gained while pregnant:"I felt more powerful than I've ever felt in my life," Knowles shares. "I felt connected to my body. I felt like I knew my purpose in the world."
The singer says she gained 50 pounds during her pregnancy – putting on the last 20 during the final month leading up to the delivery – and was determined to bounce back after baby as soon as possible.
"I lost most of my weight from breastfeeding and I encourage women to do it; It's just so good for the baby and good for yourself," Knowles, who breastfed Blue for 10 weeks, says.
Then, "about a month after" giving birth, the new mom tackled the remaining pounds with a strict diet and exercise routine.
"I counted calories. I worked out maybe three to four times a week," she shares. "I did a lot of walking in the beginning and now I'm running. But I had to work my way up. I couldn't just go right from being pregnant to running."
All the hard work – including "staying away from anything delicious" and no cheat days – has paid off.
"I'm proud that my waist came back so fast. I'm proud of that and happy, but that was mostly from the breastfeeding," the singer explains.
And not only is Knowles just "three to four pounds" away from her pre-pregnancy weight, but she has also acquired a new softness about her voluptuous body.
