Rihanna still get pre-show jitters

She's the queen of the stage and uber cool when she performs, but it seems that the Diamonds singer Rihanna still get the jitters before a show. Singer/songwriter Mikky Ekko wrote the song Stay for Rihanna's Unapologetic album. Mikky and Rihanna performed the song as a duet at the Grammys in February, and according to Mikky the singer still gets pre-performance jitters. "She walked over to me right before the curtains went up and she said, 'I'm so nervous.' And that, for me, was one of the most calming [things],' Mikky told MTV News. 'It made me feel like... [OK], it's totally natural. It reminded me of being in high school at a talent show... except it was a world stage." Who would have guessed it....
