Rihanna Spills Out Emotional 'Stay' At Grammys

Mikky Ekko joins Rih onstage to perform Unapologetic single.

Rihanna turned heads as she strutted down the 2013 Grammys red carpet in a stunning red dress on Sunday night, but the pop star definitely needed an outfit change to deliver the emotional single "Stay" from her seventh album Unapologetic.

Standing in front of a dimly lit set, Rih was dressed in a long, curve-hugging black dress, barely moving, as she belted out the tune. Though the seven-time Grammy winner is usually known for putting on high energy, dance-fueled performances, tonight she kept things simple, keeping the focus on her vocals.

Onstage with her was singer, songwriter and producer Mikky Ekko, whose name fans might recognize since he duets with her on the single. Ekko, who actually penned the original song, was also clad in all-black, complementing his three-piece suit with a black beanie hat. He sat just behind Rihanna on the stage, belting out his portion of the song as the band played in the background.

Fans were certainly moved by the performance, though many of them seemed to be fixated on Rihanna's breathtaking appearance as she sang. "Rihanna is everything. #Grammys," Jersey Shore star ‏@snooki tweeted, while @Pharrell added, "@rihanna was all emotion in that performance. #GRAMMYS"

Before the show was over, Rihanna returned to the stage to tribute Bob Marley along with Ziggy Marley, Damian Marley, Bruno Mars and Sting. Earlier in the night, she took home the very first award with "We Found Love" for Best Short Form Video, beating out the Throne's "No Church in the Wild."
