Kelsea Ballerini and Lukas Graham teamed up at the Grammys and sang a mashup of their respective hits “Peter Pan” and “7 Years.”

KELSEA BALLERINI & LUKAS GRAHAM PERFORM DUET

Ballerini wore an adventurous pantsuit with a lot of different colors, which is very different from her normal concert attire. “Every time I’ve performed ‘Peter Pan,’ I’ve worn a big, princess-y dress,” Ballerini told Billboard. “This is a different version of the song, so we wanted to make it feel different [style]-wise, too. It’s sparkly, and the structure is really beautiful and more mature.”

HOLY %!*# I JUST SANG AT THE GRAMMYS
