Taylor Swift said early Tuesday that she is “completely in shock” after three young children were killed and nearly a dozen others injured in a mass stabbing at a UK dance workshop themed to her music.

“The horror of yesterday’s attack in Southport is washing over me continuously and I’m just completely in shock,” the pop superstar said in a message posted to her Instagram stories.

“These were just little kids at a dance class,” the “Love Story” singer said of the 11 children stabbed, three of whom died and five others are still fighting for their lives.

“The loss of life and innocence and the horrendous trauma inflicted on everyone who was there,” she said of the bloodbath, which also saw two adults left in critical condition while trying to save the youngsters.

“I am at a complete loss for how to ever convey my sympathies to their families,” she wrote.

Swift’s message came as UK cops continued interviewing an unidentified 17-=year-old suspect for the shocking attack just before noon Monday at a Taylor Swift-themed yoga and dance workshop.

Witnesses said the attacker wore a “black hood” when he entered the Hart Space, which also houses a nursery and had advertised “a morning of Taylor Swift-themed yoga, dance and bracelet making.”

At least 25 children from the ages of 6 to 11 were at the event when the carnage unfolded — with the knifeman reportedly pulling up in a taxi, witnesses said.

Officers called to the scene “were shocked to find that multiple people, many of whom were children, had been subjected to a ferocious attack and had serious injuries,” Merseyside Police Chief Constable Serena Kennedy said.

“As a mom and a nana, I can’t begin to imagine the pain and suffering that the families and the victims are going through at this time,” the top cop said.

Police have yet to give a motive for the horror attack — but said Monday that it was “not currently being treated as terror-related.”
