Keith Urban and Carrie Underwood lit up the stage at the 2017 Grammys!

The country stars sang their duet "The Fighter" together at the prestigious award show on Sunday, Feb. 12 — and it's become one the most-talked-about performances of the night! As John Travolta would say, the pair were "the most dynamic duo since Danny and Sandy!" — and we couldn't agree more!

Watch Keith and Carrie sing away in the clip below!
