Lil Nas X saw Madonna’s “Madame X” gig in LA, where she sipped the younger star’s beer and offered up a future duet.

“If I drink this, I’d be getting some of your backwash?” she asked, before taking a swig. “Kinda sharp, your backwash. Might cut my tongue.”

They sang a snippet of his hit “Old Town Road” and chatted about her New York farm. “I expect you to show up to my horse farm. I’m going to show you what to do with a horse for real … And then we can make a song about chickens, because I’ve got chickens, too,” she said.

The Material Girl, 61, grilled Lil Nas, 20, on his career: “You in here for the short distance or the long distance?” “Long, for sure,” he replied.

Her advice? “Work hard. Earn it, baby.” “I promise you I will,” he said.
