An Austrian man who authorities said pledged allegiance to the Islamic State terrorist group pleaded guilty Tuesday to a foiled plot to attack one of Taylor Swift’s concerts in Vienna.

A TERROR plotter set out to massacre Taylor Swift fans with a car, machetes and a bomb to look “cool” like his jihadist hero, a court was told yesterday.

"We established this thing that we love to do, and we call it the rant bridge," she said.
