Rihanna Goes Topless Again—This Time in Hawaii

Singer, no stranger to stripping down, posts some revealing pics on Facebook

Aloha!

Rihanna is, once again, doing what she does best. (Other than singing, of course.)

On Monday, the Barbadian beauty decided to post some sexy pics to her Facebook page from her January vacation in Hawaii.

But naturally, the ones that caught everybody's eye were those featuring Ri-Ri with her bikini top off.

While taking a dip under a waterfall, the songstress playfully waves it in the air as she shields her exposed chest with her hand.

Other shots posted show the 24-year-old snorkeling, sunbathing, frolicking on the beach, surfing and horseback riding.

All while (gasp!) completely covered up.
