Country and pop united at the 59th Grammy Awards when Kelsea Ballerini took the stage to perform a duet with the lead singer of Lukas Graham, Lukas Forchhammer.

After an introduction from radio personality and former American Idol host Ryan Seacrest, the two rising stars joined forces for a combined performance of their No. 1 hits, Ballerini's "Peter Pan" and Graham's "7 Years."

Dressed in a one-piece glittery suit and high ponytail, Ballerini showed off her sweet vocals while singing her third No. 1 song in an orchestrated performance that melded the stars' songs together with choruses from her track and "7 Years." Ballerini offered a stripped down version of "Peter Pan" with a more acoustic vibe, as the two stars complimented each other nicely with their vocal abilities. Lukas Graham are nominated for three of the night's awards for "7 Years," including Song of the Year.
