BEYONCÉ

PEOPLE's 2012 World's Most Beautiful Woman Beyoncé and husband Jay-Z gave the world their first glimpse of daughter Blue Ivy through a Tumblr account created in her honor. "We welcome you to share in our joy," the new mom shared in a handwritten note four weeks after the January birth of her daughter. "Thank you for respecting our privacy during this beautiful time in our lives."
