After wowing in a sexy, chic custom Giorgio Armani dress that she helped design, Rihanna went back to her edgy ways and opted for a leather hotpants and and sheer-shirt ensemble at Sunday's Grammys in L.A.

The singer, 23, performed her hit "We Found Love" while rocking an all-black, midriff-baring getup: short shorts, black tights and a sheer shirt that exposed her black $220 Eres bra.

The Barbados beauty, who accessorized with a ring from Robert Lee Morris, a body chain and a $1,950 David Yurman necklace, then stayed on stage for an unexpected duet with Coldplay for their song "Princess of China."
