Katy Perry Looks Stunned as TikToker Serenades Her With ‘Prism’ Deep Cut at Coachella

Katy Perry was on both the giving and receiving ends of surprise performances at this year’s Coachella.

Shortly after the pop star made a guest appearance onstage at best friend Mia Moretti’s festival set, she was approached by TikToker Harry Daniels for an impromptu performance of a Prism deep cut — which, a stunned Perry revealed, she just so happened to write about her DJ BFF more than a decade ago.

In a clip posted Monday (April 15), Daniels approaches Perry — who wears a T-shirt with husband Orlando Bloom’s Lord of the Rings character on it — and starts belting out a few lines from her 2013 song “International Smile.” As the American Idol judge’s eyes widen in shock, she looks frantically around and shouts, “Where’s Mia?”

She then explains excitedly: “My best friend that just played Coachella, that song’s about her!”

“I got really nervous to sing for katy and i blanked,” Daniels captioned the video. “the only song i could remember was this one deep cut from 2013.”

The comedian — who’s known for singing in front of unwitting celebrities such as Billie Eilish, Ellie Goulding and, very recently, President Joe Biden — also crossed paths with Gwen Stefani, Paris Hilton, Tyga, Becky G, Reneé Rapp and Wallows’ Dylan Minnette during the first weekend of Coachella 2024, which kicked off Friday. The festival will pick up again April 19, with headliners Lana Del Rey, Tyler, the Creator and Doja Cat returning for round two.

Perry was present at day 3 of this year’s event, joining her longtime pal behind the DJ booth on the DoLab stage Sunday (April 14). At one point, she shot fake dollar bills into the crowd with a money gun while modeling a bikini tee from Moretti’s merch line.

Other surprise guests at Coachella 2024 were Kesha, who showed up during Rapp’s set, Olivia Rodrigo, who appeared during Stefani and No Doubt’s performance, and Eilish, who joined Del Rey on the main stage.
