Unbelievable : (see Video) Taylor Swift suffered a rare onstage mishap as she nearly fell off her chair during a steamy performance on her The Eras Tour in Tokyo on Wednesday…

The star, 34, who will race back to the US at the weekend for the Super Bowl to support Travis Kelce,

was performing a racy rendition of hit Vigilante S**t – which sees her squat with her legs open before slowly descending onto a chair,

However, the star, clad in a midnight blue leotard, misjudged the chair’s position and was seen stumbling before regaining her composure.
