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.Styles, 28, jumped in for the chorus of “Man, I Feel Like a Woman” and the pair danced playfully on stage to resounding applause.At the end of the song, the two hugged before sitting on two stools. “In the car, with my mother as a child, this lady taught me to sing,” said Styles. “She also told me that men are trash. To you, for the memories you gave me with my mother, I will be forever grateful,” he said, addressing Twain.”I am so honored and thrilled to be here,” said Twain. “I’m kind of lost for words. I’m a bit star-struck, what can I say?” The pair then performed “You’re Still The One,” a song Twain noted she wrote while Styles was just “a little kid.”After the exuberant duet, Twain took to Twitter to laud her co-star’s performance. “I mean c’mon … HARRY STYLES,” she wrote.Styles also performed his record-breaking new single “As It Was” during his performance.Styles’ set began at 11:35 on Friday, according to the Coachella schedule. Other headliners from the star-studded weekend include Billie Eilish, Arcade Fire, Carly Rae Jepsen, and the Weeknd.
