Happy birthday, Beyonce! With a prolific career that began in the '90s with her chart-topping girl group Destiny's Child, it's hard to remember that the beatific performer is only 31 years old today. But Bey has had a landmark year that rivals even all the others.

From welcoming her first child, daughter Blue Ivy Carter, to sharing hundreds of candids on her first Tumblr blog, to being crowned People magazine's "Most Beautiful Person," the new mom and stadium-seller shows no signs of stopping. With her marriage to Jay-Z four years strong, Beyonce also serves as a role model for women everywhere on how to have your cake and eat it too. No wonder everyone wants to be her best friend.
