Harry Styles performs on stage with 'star-struck' Shania Twain at Coachella

Harry Styles treated fans at his Coachella concert on Friday to an unexpected guest: Shania Twain. The pair performed Twain's hit 'You're Still The One.'

Her appearance didn't come until the last few minutes of Styles' set. The iconic refrain of Twain's "Man, I Feel Like a Woman" began to play as soon as Styles had finished performing a classic from his boy band days with One Direction, "What Makes You Beautiful."

Styles, dressed in a low-cut jumpsuit emblazoned with rainbow sequins, appeared to look confused until Twain, 56, appeared, rising on a platform from behind the stage dressed in a matching sequined dress and white go-go boots.

"Let's go girls," said the queen of country pop, in a video posted by Coachella.

Styles, 28, jumped in for the chorus of "Man, I Feel Like a Woman" and the pair danced playfully on stage to resounding applause.
