Donald Trump flipped off by Bill Burr’s wife, Nia Renée Hill, at UFC match

Mocking birds?

Bill Burr’s wife, actress Nia Renée Hill, was caught flipping off former President Donald Trump with both her middle fingers at an Ultimate Fighting Championship match Saturday at Madison Square Garden.

An avid UFC fan, Trump entered the arena to a loud ovation before the featherweight fight between Diego Lopes and Pat Sabatini. He was accompanied by Kid Rock, Tucker Carlson, Dana White and son Don Jr.

Arena cameras panned to him — and in the background Hill, 54, can be seen raising her middle fingers at his back as she sits in her seat.

Trump, 77, seemed utterly clueless about the gesture as he continued to scan the room. Burr’s head, meanwhile, was turned in the opposite direction.

The Post reached out to a rep for Burr, 55, for comment.

The clip of Hill giving Trump the double bird circulated on social media, especially on the bird app X, where it sparked backlash for the “Old Dads” actress.

“So trashy. Surprise, surprise,” tweeted one person.

“This is what free speech is all about! I fought for it, does not mean I have to agree with it! Do your thing young lady,” chirped another.

“She is speaking on behalf of the majority of Americans,” insisted a third.

“Nia Renee Hill just made a lot of fans tonight,” another declared.

“Donald Trump walked into an arena that holds 20,000 people and 19,999 people were so happy. And then there was Bill Burr’s wife,” The Post Millennial editor Libby Emmons posted.

Burr — who has starred on “Breaking Bad” and “The Mandalorian” — has released several comedy specials, including “I’m Sorry You Feel That Way,” “Walk Your Way Out,” and “Paper Tiger.”

He and Hill married in 2013 and have two children.
