Looking drop-dead sexy in a very low-cut black silk custom Giorgio Armani gown with a thigh-high slit and a mermaid train, Rihanna stole the show on the red carpet at the 2012 Grammy Awards in LA, on Sunday evening.
The S&M singer, who's set to perform at tonight's awards ceremony, paired her daring gown with Neil Lane jewels, Jacquie Aiche body necklaces, Christian Louboutin stilettos, and a Jimmy Choo clutch.
This show marks the first time Rihanna and ex-bf Chris Brown have appeared at the same awards show since his attack on her in 2009, which was also on the eve of the Grammys that year.
Riri just might be the "Only Girl in the World" who can rock such a sultry ensemble! Work it, girl!
