Beyoncé Knowles is a woman in Hollywood that just can't be beat. The 16-time Grammy winner and first time mother has been named People magazine's 2012 World's Most Beautiful Woman. ""I feel more beautiful than I've ever felt because I've given birth,"" the 30-year-old singer - who welcomed her daughter Blue Ivy Carter with husband Jay-Z, 42, on Jan. 7 - tells the mag. ""I have never felt so connected, never felt like I had such a purpose on this earth.""

While she did come out with the album, 4, in 2011, for Beyoncé, motherhood trumps any other achievement. ""She's just the cutest thing,"" the proud mama gushes. ""She's her own person.""

""The best thing about having a daughter is having a true legacy,"" Beyoncé adds. ""The word 'love' means something completely different now.""
