Grammy-award winning singer Rihanna debuted her new, bleach-blond shag-style haircut on Twitter last night during a photo shoot for Elle magazine.

"#Back2Work 1st Cover of the year!!!! #ELLE" she wrote. "I dyed it for #ELLE," she told a fan.

Rihanna, 23, snapped a second picture of her new weave, posing seductively in an off-the-shoulder sweater, cut-off jean shorts, and boots she admits are a bit "stripperish."

Later that night, Rihanna took her new haircut (and her stripper boots) out for a night on the town — first, she and some girlfriends hit up the Staples Center to watch the L.A. Clippers play the Denver Nuggets, and then she made an appearance at the Roxbury nightclub in Hollywood.

Hm. We guess blondes really do have more fun.
