Country star Miranda Lambert dumped a bowl of salad onto a woman’s lap during a heated exchange at a Nashville steakhouse, according to a report.

“The House That Built Me” singer was dining with her mom and a family friend at the Stoney River Steakhouse when an older man started a fight with the pal in the restroom, TMZ reported.

The two men apparently began arguing about millennials and their cellphones, according to the gossip site.

Eyewitnesses said the two-time Grammy winner had to be held back after the man stopped by their table and began screaming.

Lambert, 35, stormed over to the man’s wife and dumped the bowl of salad onto her lap, according to TMZ.

By the time cops arrived, Miranda and her party had left the eatery. No police report was filed, the outlet reported.

Lambert is no stranger to controversy. In November, she claimed the only reason her song “Drowns the Whiskey” with Jason Aldean went to No. 1 was because she performed it with a man.

“Yes, I had to sing with someone with a penis to get a number one,” Lambert told The Washington Post. “I do like this person, Jason Aldean, a lot . . . so it was a great song with an old friend.”

She added: ‘It is interesting that I haven’t had even a Top 20 in a long, long time, and then it goes number one because it’s a dude. But you know — if we went and looked at how many singles or records were sold for the Top 10 songs right now, I’d probably triple it on record sales. So it doesn’t matter.”

Reps for Lambert did not immediately respond Wednesday to messages from The Post.
