"I feel more beautiful than I've ever felt because I've given birth," Beyoncé tells the magazine.
The songstress, who gave birth to daughter Blue Ivy Carter on January 7, 2012, says having a child has given her life more purpose. "The best thing about having a daughter is having a true legacy," she says. "The word 'love' means something completely different now."
Asked who Blue most resembles, Beyoncé quips, "She's just the cutest thing. She looks like Blue. She's her own person."
The singer plans to make her must anticipated stage comeback this Memorial Day weekend with three exclusive concerts at Atlantic City's newest resort, Revel.
