Swifties argue over behavior in theaters showing Taylor Swift film

There’s “Bad Blood” between Taylor Swift fans over how to behave in her movie.

Swifties across the nation are getting into arguments over whether it’s OK to stand up and sing, dance, and videotape — as if you are at a concert.

Or should they politely sit in their seat and watch the hit concert movie, “Taylor Swift: The Eras Tour?”

Erica Vuitton saw the film at the Village East by Angelika in the East Village, where fellow movie-goers didn’t appreciate her enthusiasm.

“Several people complained to the theater about me singing and dancing in the front,” she told The Post.

“By the time a theater employee approached me, I was rescued by a gang of tweens who had come down and were dancing with me. Nonetheless, many were still complaining.”

Floridian Victoria McBrayer also faced off against disapproving fans, who gave her “dirty-a– looks” for singing at her local theater.

One woman reprimanded her during “I Knew You Were Trouble.”

“The girl turns around and goes, ‘You’re singing too loud and you’re ruining this experience for me,’” recalled McBrayer, 27, who saw the flick with her husband and their 8-year-old daughter, Cassadee-Lynn.

“I said to her, ‘Then why are you here? This is a concert experience.’ And she said, ‘You can sing, but don’t be annoying about it.’”

Alabama resident Jennifer Smith was threatened with a fine for having her cell phone camera flash on to film her 10-year-old daughter dancing.

“I guess someone complained, so an AMC employee came down and told our group, ‘If you turn your flash on one more time, you’re gonna be charged a $50 fine,’” Smith, 39, said.

“One of the moms chased him out and told him, ‘This is not the experience that Taylor Swift wanted. We’re just having fun with our little girls.’”

Swift herself has encouraged the revelry in theaters and posted on X, “I’ve been watching videos of you guys in the theaters dancing and prancing and recreating choreography . . . wow, just thank you!!!”

After negotiations with movie studios failed, Swift made an agreement with AMC Theatres for its distribution.

On its website, AMC lists rules for behavior while viewing the film, which include to “not record the concert film on our big screen” and “not dance on our seats or block other guests from viewing.”

However, AMC does allow its guests to get down and belt out some of Swift’s chart-topping songs.

After her uncomfortable encounter, McBrayer said she was still able to have her own fun and get back at the person who complained — when Swift’s song “Shake It Off” came on.

“I was singing, ‘Haters gonna hate, hate, hate’ as loud as I could to her,’” she said.
