MANLA, Philippines – US television network CBS warned stars against revealing too much skin during the 2013 Grammy Awards, but singer-songwriter Rihanna doesn’t plan on playing by the rules.

Hollywoodlife.com reports that Rihanna will be wearing “something very sexy by a few of her favorite designers.” She will perform a number during the awards show.

The singer, known for her figure-hugging outfits and signature style, will also be going to the Grammys with her on-again, off-again partner Chris Brown.

CBS, which will broadcast the show live, issued an advisory to stars asking them to avoid showing too much flesh – be it breasts or nipples.

Is Rihanna living up to her “good girl gone bad” image?

The 55^th Grammy Awards airs Sunday night, February 10, in the United States. – Rappler.com
