Kacey Musgraves kicked off her "Middle of Nowhere" tour in dazzling fashion ... floating above the stage, sitting atop a glittering mechanism that appeared to resemble the body parts of a man's nether region.

Check it out -- the country star is singing her 2026 song "Rhinestoned" as she sits on a floating chair that fans have dubbed "disco balls" for obvious reasons.

She joked about the suggestive prop during her performance at Chicago's United Center, telling the crowd ... "This is what it looks like when no one tells me no!"

We wouldn't expect anything less from the country crooner -- she just launched her own line of limited edition lubricant called Drought Drops, which she's said "keeps the dry spells away and the good times coming."

"Dry Spell" is the lead single from Kacey Musgraves' album "Middle of Nowhere," which she released in March of this year. The song's witty lyrics talk about the frustration of going an extended period without sex.

Looks like she's making light of the dry situation!
