The Coachella music festival has kicked off with surprise guest actor Susan Sarandon featuring in pop star Sabrina Carpenter's headlining performance on Friday.

The actor delivered a monologue as an older version of 26-year-old Carpenter in the middle of her set. Other stars who featured in the singer's classic Hollywood-themed gig were comedian Will Ferrell and actor Sam Elliott.

The massive festival in the California desert draws more than 100,000 people daily over two weekends, according to police from the city of Indio.

This year, weather agencies have warned of wind and dust in the area, with strong winds forcing the festival to cancel a set by DJ Anyma after Carpenter's performance.

“Due to strong wind conditions affecting Anyma's stage build, he is unable to perform tonight,” the Coachella Valley Music and Arts Festival said in a statement on Instagram on Friday. “Coachella and Anyma have made this decision together with your safety as the priority.”

On Saturday, Justin Bieber will headline the festival, followed by Karol G on Sunday. A number of UK artists including Wet Leg, Lambrini Girls, Little Simz, and FKA Twigs are also on the bill.
