Kacey Musgraves is taking home the Grammy for best country solo performance!

“What the heck!” she said on the red carpet of winning the award. “This is crazy!”

She then took a shot of tequila in celebration. “It’s real tequila,” she joked. “Not water.”

The singer won the prize for her song “Butterflies,”beating out fellow nominees Loretta Lynn (“Wouldn’t It Be Great?”), Maren Morris (“Mona Lisas and Mad Hatters”), Keith Urban (“Parallel Line”) and Chris Stapleton (“Millionaire”).

Her genre-defying track was inspired by how she fell in love with her now-husband Ruston Kelly.

“‘Butterflies’ is one of my favorite songs on the record,” Musgraves said told CMT in a radio interview in May. “Everything from the lyrics down to the production really represents this floaty, dreamy feeling that I got as soon as he came into my life.”
