Camila Cabello was the surprise guest artist for Lana Del Rey‘s headlining Coachella set on Friday night.

Del Rey temporarily left the stage after singing her song “Bartender” as Cabello launched into a surprise performance of her new single “I Luv It” from her forthcoming fourth studio album. Lana joined Cabello through some verses but mostly watched and danced from the balcony of her palace-like stage.

Cabello was backed by a crew of dancers who recreated the robotic choreography seen in the single’s matching music video which also features collaborator, Playboi Carti (Carti was not present on stage). Del Rey joined Cabello on the floor of the stage during Carti’s verse and placed her hands around Cabello’s waist as the two shared a playful spin.

“I luv it, I luv it, I luv it, I luv it,” Del Rey sang back to Cabello as the pop singer closed the song. She continued, “[Camila] is my girl, I have so much fun with her. I love this song and thank you so much angel, for coming and singing with me.”

Cabello responded, “This is an honor for me, you’re one of my favorite artists of all time. I love you so much.”

Del Rey’s week one Coachella performance welcomed recent collaborators Jack Antonoff and Jon Batiste, who again joined Del Rey again on Friday night. Both Antonoff and Batiste are also performing their own sets (Antonoff as the lead singer of the band Bleachers) at the festival. Billie Eilish also joined Del Rey who turned up for a surprise pair of duets of Eilish’s “Ocean Eyes,” and Del Rey’s “Video Games.”
