Billie Eilish, the headline act at Coachella on Sunday, apologised for ‘not being Beyoncé,’ according to Page Six.

Eilish, 20, became the youngest artist to headline the California music festival on Saturday, and she constantly poked fun at herself on stage to show how bizarre the situation was for her.

Towards the end of her concert, the Bad Guy singer offered a special shout out to 2018 headliner Beyoncé, telling the crowd, “Thank you, Coachella!” Sorry, but I’m not Beyoncé.”

She also joked earlier in the night that she “shouldn’t be headlining” Coachella and that she was “so (expletive) happy” to be performing at the event.

“This is really a dream come true,” the Grammy winner stated. “I’m going insane.”

During her show, Eilish pulled out some unexpected guests, including Khalid, a collaborator, and Damon Albarn, the leader of Gorillaz.
