Alicia Keys & Maren Morris twinkle with 'Once' at the 2017 Grammy Awards

A newly-minted Grammy winner, country newcomer Maren Morris made an indelible impression tonight (Feb. 12) at the 59th Grammy Awards. Taking to the stage in a sultry outfit worthy of Queen Cleopatra, she whipped out her swirling, tender song "Once," a cut from her nominated debut album Hero. R&B veteran Alicia Keys--who donned a matching, glittery pantsuit--joined the breakout star for a soulful and slinky rendition of the track. As the song crescendo over luscious strings, the legendary diva and the diva-in-the-making pushed and pulled on the vocal power, giving each other a moment to truly shine on the biggest stage in the musical world.

Earlier in the evening, Morris gave an emotional acceptance speech upon claiming Best Country Solo Performance for her platinum-selling, Top 10 hit "My Church." “Oh my goodness, this is so crazy,” Morris told the crowd. “Thank you to the Recording Academy. 11 years ago, I went to the first ever Grammy camp. It was the first time I ever flew on a plane by myself to L.A. and it’s crazy to be here a decade later. Thank you guys so much. This is amazing, and the fans, thank you for giving me the most incredible year of my life.”

Her album Hero, which contains her latest hit single "80s Mercedes," was nominated for Best Country Album.
