The truth behind why Taylor Swift has yet to make a statement regarding the foiled terror plot that forced her to cancel three sold-out concerts last week.

The 34-year-old singer will kick off five sold-out nights at ­Wembley Stadium on Thursday — eight days after cancelling three shows in Vienna when police foiled an IS terror plot.

Since the shocking plan was exposed, Swift has fallen unusually silent and hasn’t been heard from since.

Some backlash from fans began to emerge across social media in response, with some calling out the star over her silence.

However, now the truth behind the superstar’s reason for not speaking out has been revealed.

“Taylor’s security and of those around her has always been paramount, but even more so now,” a source told The Sun.

According to the insider, Swift has been told by authorities to remain quiet while preparations for her sold-out Wembley shows is underway.

“She and her dancers were told to ‘go to ground for their own safety’ in light of the Vienna threat. That’s why nothing has been said about the cancelled shows beyond the promoter’s statement.”

Over the weekend, the mum of Sam McWilliams — one of Taylor’s dancers — was also reported to have told a fan: “They’re all on lockdown but doing OK.”

It comes after the lawyer for the 19-year-old arrested over the Austria plot claimed the teen was a fantasist who just wanted to be “cool”.

She said: “He says the bomb wasn’t of good enough quality — it wouldn’t have worked.” But he had researched online on how to build a device, she added.

Speaking to the UK’s Sky News, London mayor Sadiq Khan confirmed that plans are going full-steam ahead for the pop star’s five sold-out nights at Wembley Stadium, which are set to kick off next week. “We have a huge amount of experience in policing these events. We’re never complacent, many lessons were learned after the awful Manchester Arena attack,” Mr Khan said, referencing the 2017 tragedy at an Ariana Grande concert that left 23 — including the assailant — dead.

“The police work closely, not just with City Hall and with councils, but also with those who host concerts, like the Taylor Swift concert coming up over the next couple of weeks.”

He added: “I’m sure Vienna has got its own reasons for deciding to cancel the Taylor Swift concerts, we’re going to carry on, working closely with police [and] ensuring that the Taylor Swift concerts can take place in London safely.”
