Beyoncé is “sandylicious.”

The sexy star singer frolicked on the beaches of Hawaii yesterday then got buried up to her neck by friends.

At one point, only Beyoncé’s head could be seen sticking out of the sand before she emerged in her multicolored one-piece bathing suit, still covered in grit but laughing loudly.

The “Single Ladies” singer joined in building a sand castle with a group of kids.

Her rap-mogul husband, Jay-Z, stood nearby snapping pics with a digital camera for posterity.
