Rihanna steamed up the red carpet of the 2012 Grammy Awards on Sunday night, wearing a dangerously sexy Giorgio Armani gown and dripping in Neil Lane bling – but what you may not know, is that her manicure featured 24-karat gold polish and was worth a whopping $5,000!

Rihanna’s manicurist Kimmie Kyees painted her nails in Red Carpet Manicure’s Amor 24 gel polish, which retails for $5,000 a bottle! For an extra touch of bling, she added a dollar sign chart to her pinkie finger.
