Gracing the cover of People's Most Beautiful People issue in April 2012—four months after the birth of her first child, Blue—Beyonce told the magazine that she was back to her pre-pregnancy weight and felt "more beautiful than ever." In fact, she flaunted her famous curves just weeks after giving birth when she wore a figure-hugging dress to husband Jay-Z's Carnegie Hall concert in February. "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 told People.
