Beyonce plus bikinis plus beach plus music equals bliss! The superstar, 31, rocks her world-famous beach body in a just-released new H&M commercial, in which she models a slew of sexy two-pieces and more body-hugging beachwear against a pristine sand-and-surf setting. A big bonus for Beyonce's fans? The 1:30 minute spot also features Beyonce singing and dancing to a brand-new song, "Standing on the Sun." (Sometimes aided by a crew of backup dancers, the Grammy winner splashes around in the waves in both blonde and jet-black hair.)

In her third revealed track from her upcoming fifth album, Beyonce croons "I can't deny your desire, feel like I'm on fire. When you touch me, I feel the flame they can never feel." So far, Blue Ivy's mom (currently on her world Mrs. Carter Show World Tour) has given sneak peeks of "Bow Down/I Been On" and "Grown Woman." The release date for the album has not yet been released, and her concert setlist is mostly comprised of older classics.

25 percent of proceeds from the new swimwear collection, called H&M for Water, will be donated to H&M for WaterAid, which helps raise money for the world's poorest people to gain access to safe water.
