Indio, California – All hail #Harrychella!

Fans got rocked by a double dose of star power to kick off weekend two of Coachella, as Harry Styles took the stage for his headlining set of the music festival in the Cali desert on Friday night.

The 28-year-old heartthrob performed a stellar set that included his hits Watermelon Sugar, Sign of the Times, and Adore You sprinkled with his suave dance moves and a pink metallic open vest ensemble.

But the former boybander whipped out the surprise of all surprises when he was joined onstage by none other than Lizzo.

The two pulled off another unexpected throwback, à la Harry's duet during Coachella weekend one with Shania Twain on her classic hit Man! I Feel Like A Woman.

This time, he donned a feathered boa and was flanked by the Truth Hurts singer for Gloria Gaynor's classic disco singalong, I Will Survive.

Then the pair performed one of Harry's own golden oldies, One Direction's What Makes You Beautiful, which is marking its 10-year anniversary this year.

Lizzo dropped the bomb on her TikTok on Friday that she was "bored" and on her way to Coachella. It follows her stint last weekend performing as the host and musical guest of Saturday Night Live.

"Proud of you @harrystyles," she wrote under an Instagram selfie of the duo after the Coachella appearance. "Thank u for having me."

Both Harry and Lizzo have new albums on the way, with Harry’s House coming on May 20 and Special dropping July 15.

Fans are eager to see what else is in store for Coachella this weekend, and if there will be any more surprise guests between Billie Eilish headlining Saturday and The Weeknd and Swedish House Mafia closing out the fest on Sunday night.
