Rihanna is looking hardcore in the latest campaign for Armani Jeans ... bleached blonde hair and all!

The 23-year-old stunner, snapped by celebrity photographer Steven Klein, sports tight jeans, black boots and a cropped top exposing her toned tummy. And in a second shot, Rihanna lost the jeans all together. We're not complaining.

Seems as though RiRi can pull off just about any look!
