Colorado Rep. Lauren Boebert called a pregnant woman “a sad and miserable person” after she asked the Republican lawmaker to stop vaping during the “Beetlejuice” performance she and her date were later kicked out of on Sunday, according to a report.

The firebrand’s foul remark came after she had told the mom-to-be “no” when the fellow Denver theatergoer asked her to put her vaping pen down, the Denver Post reported Thursday.

“These people in front of us were outrageous,” the woman, who requested anonymity, told the newspaper.

“I’ve never seen anyone act like that before.”

The behavior of Boebert, 36, and her date — Democratic Aspen bar owner Quinn Gallagher, 46 — eventually led to their dismissal from the Buell Theatre after fellow audience members complained the two were being loud.

Staffers accused the pair of vaping, singing and recording during the show, the Denver Post previously reported.

The pregnant woman, who is in her 30s, said she didn’t know the woman in front of her was Boebert.

The fed-up woman, who was sitting behind the couple, went to ask an usher if there were any seats available away from the troublemakers.

“The usher said, ‘You’re not the first complaint we had,’” she told the outlet.

When the patron got back to her seats with her husband, Boebert reportedly lashed out, calling the woman “a sad and miserable person,” she recalled.

“The guy she was with offered to buy me and my husband cocktails,” the woman said. “I’m pregnant!”

She provided the Denver Post with a receipt to prove she was at the show and a photo showing she had been sitting behind Boebert.

The lawmaker, a mother of four boys and grandmother of one, filed for divorce from Jayson, her husband of 18 years, in May, citing “irreconcilable differences.”

As she and Gallagher were being booted, Boebert allegedly said, “‘Do you know who I am,’ ‘I am on the board’ (and) ‘I will be contacting the mayor,’” according to an incident report.

Boerbert’s office denied she was vaping to The Post Wednesday, saying there had been “a misunderstanding from someone sitting near her” who hadn’t noticed the “heavy fog machines and electronic cigarettes used during the play.”

The congresswoman did admit, however, that she had a raucous time at the show.

“It’s true, I did thoroughly enjoy the AMAZING Beetlejuice at the Buell Theatre and I plead guilty to laughing and singing too loud!” she tweeted this week.

“Everyone should go see it if you get the chance this week and please let me know how it ends!”
