Rihanna performed "Stay" at the 2013 Grammy Awards.

In a tight-fitting black dress, she was joined by Mikky Ekko, her collaborator on the song. The track is the second single from Unapologetic, and while it was an odd choice -- considering it's not very popular yet -- perhaps that's why she performed it in the first place.

Notably, Chris Brown gave his girl a standing ovation after the performance.

Let us know what you think? Should she have performed something else or did she 'kill it'?
