Taylor Swift ‘completely in shock’ after Southport mass stabbing

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

The pop star said she is still taking in “the horror” of the attack, in which a 17-year-old boy was arrested on suspicion of attempted murder after two young children were killed and 11 others injured, including two hero adults trying to save the youngsters and six children still in critical condition Tuesday.

“These were just little kids at a dance class,” the “Love Story” singer noted in a post on her Instagram stories Tuesday.

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

The horrifying mass stabbing unfolded just before noon in Southport, in northwest England, at a yoga and dance workshop set to Swift’s music.

Two children died in the attack while nine others were injured including six left fighting for their lives — along with two adults left in critical condition from being stabbed as they “were bravely trying to protect” the kids, Merseyside Police Chief Constable Serena Kennedy said.

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,” 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.”

A 17-year-old male was arrested, police said — adding that the attack was “not currently being treated as terror-related.”

Police have not shared a possible motive for the attack.
