Taylor Swift's dancer pulls funny face on stage…her response is perfect

She may be singing an angst-ridden song about her frenemy, but Taylor Swift nearly cracked up during her latest performance of number one hit 'Bad Blood'.

It's all thanks to her cheeky dancer Christian Henderson, who pulled one hell of a freaky face at Tay-Tay during her 1989 concert in Pittsburgh, Pennsylvania.

It's the stuff of horror movies – but Taylor handles it like the pro she is. Come on, we know you're just dying to ROFL, Tay! Watch above.

"Every night during 'Bad Blood', the face @cd_henderson makes gets worse and worse/better and better," she tweeted.

"We have fun…," the handsome dancer wrote back.

No bad blood there, obvs.
