Listen to Beyonce on iHeartRadio

(Yahoo!) - Beyoncé is sexy and sizzling as the famous face of H&M's 2013 summer campaign! Known to lend her iconic image to more upscale and sophisticated labels like Tommy Hilfiger and Armani, Queen B seems to be going back in time, sporting teeny-weeny bikinis and modeling for the budget-friendly brand.

Not only did the 31-year-old superstar lend her good looks to the label, but she also collaborated and helped design the pieces! She said in a press release, "I've always like H&M's focus on fun and affordable fashion. I really loved the concept we collaborated on to explore the different emotions of women represented by the four elements – fire, water, earth and wind."

Her body is definitely bootylicious in those teeny bikinis, and she's clearly showing us she's in tiptop shape for her upcoming "Mrs. Carter Show World Tour," which kicks off April 15.
