The “Euphoria” star hit the stage to perform a surprise duet with Labrinth over the weekend.

A message appearing to take a dig at the “As It Was” singer was displayed on the screens onstage during the Puerto Rican rapper's performance.

“There was no malfunction,” said former hockey player Dan Powers. “He just straight-up was like, ‘F**k this. I’m not doing this anymore.’”

The headliner withdrew from the festival due to "two fractures and a sprain in his left leg," a representative said.
