Kacey Musgraves is all set for her appearance Saturday (May 12) as the musical guest on Saturday Night Live, and it seems she's even got her comedic chops up and ready, as well.

In a funny promo video posted for the show which Musgraves shared on her Instagram account, I Feel Pretty actress Amy Schumer—who is guest-hosting the second-to-last episode of Season 43—introduces Musgraves, and notes in bubbly fashion, "I think this is going to be a great show."

Cast member Aidy Bryant agrees. "Probably the best of the season!"

And Musgraves throws in enthusiastically, "Probably the best show ever," to which Schumer cuts her down with a dry, "Yeah, relax, okay?"

Musgraves will be making her Studio 8H debut on the 12th, and she's planning a busy schedule for the rest of the year. She recently released her most recent studio album, Golden Hour, which debuted at No. 1 on Billboard's Top Country Album chart, and will hit the road with former One Direction singer Harry Styles on his Live on Tour roadshow beginning in June. She will also headline her own Oh, What a World Tour beginning in October in Amsterdam. That tour will visit England, Scotland and Ireland before wrapping in November.
