The Grammy winner is in the middle of a four-night stand at the Ryman.

Kacey Musgraves is making the most of her sold-out four-night stand at Nashville's legendary Ryman Auditorium. In what amounts to a Grammy Awards victory lap, the album of the year winner invited a very special guest to join her on stage on Thursday (Feb. 28) to the delight of the night two audience. A night after jamming with Paramore's Hayley Williams, Musgraves really threw the crowd a curveball when she invited rapper CeeLo Green out for a spirited, mariachi-style cover of his group Gnarls Barkley's signature 2006 hit, "Crazy."   

With Musgraves strumming an acoustic guitar and the band giving the soul smash a giddy-up tempo, the two vocalists remade the song into two-step shuffle as they do-si-do'd around each other.   

   

Among those losing their minds was Dashboard Confessional's Chris Carrabba.

Musgraves, whose Golden Hour triumphed at the Grammys two weeks ago, jammed on Cyndi Lauper's "Girls Just Wanna Have Fun" on Wednesday night; her Ryman run continues on Friday night (March 1).
