Rihanna can sing and dance, but now she's taking a turn at fashion designing as well. She dazzled on the red carpet in a black dress with a plunging neckline that she collaborated with Armani to create. And it’s not a new collabo: Rihanna has appeared in ads for Emporio Armani Underwear and for the Italian fashion house’s jeans collection. But that doesn't mean that Armani immediately trusted Rihanna's design skills. "He trusts my designs a little bit now," laughed Rihanna. Trust aside, her Grammy get-up was more about vision. "I wanted simple, sexy, gangster," she said of her look. "I wanted Michelle Pfeiffer in 'Scarface.’"
