Grammys 2012

Really, dude?

Just three years after Chris Brown pleaded guilty to felony assault for a violent incident involving then-girlfriend Rihanna, the “Beautiful People” singer is apparently treating his criminal history like a joke.

Rihanna and Katy Perry looked as fabulous as ever at the 54th Annual Grammy Awards on February 12. The ladies, who went in with a combined total of eight Grammy nominations, delivered killer performances — and Rihanna took home two statues for Kanye West’s “All of the Lights,” a collaborative effort.

If you thought the plunging, backless gown Rihanna wore to the 2012 Grammy Awards was over-the-top, get this: The singer was also sporting 24-karat gold nail polish.

The polish, Red Carpet Manicure’s “Amor 24,” runs $5,000 per bottle, and Rihanna highlighted its steep price with a tiny gold dollar sign charm on the pinky nail of her left hand.
