Who runs the world? Beyoncé! Kicking off her Mrs. Carter Show World Tour today in Serbia, H&M decided to add to the fire that is Queen Bey by debuting bikini images of the superstar from the "Beyoncé as Mrs. Carter in H&M" campaign. 

The 31-year old mommy shows off her hot body in brightly colored bikinis, pops of color on her lips and a flower accent in her hair. After seeing these pictures, we're sure everyone will be hitting the gym. Inspiration courtesy of Mrs. Carter herself!
