Lorde suffers 'cottonmouth' during surprise Coachella performance

Lorde says she got "cottonmouth" during a surprise appearance on stage at Coachella.

The Kiwi pop star stunned fans when she appeared on stage to perform with British duo Disclosure at Coachella, joining them to perform their hit song Magnets.

The singer later posted a photo of her performing on stage to Instagram, writing "cottonmouth" in the caption. Lorde performed in front of thousands of people at the Californian festival and no doubt was feeling a little nervous about the experience.

An onlooker told People that "they were all having a great time."

Lorde also posted her own pictures to Instagram from her time at Coachella, including a photo of her dancing on stage with Disclosure and a poolsides pics, one captioned "pool girl sleep from last night's dancing".

Coachella is an annual music and arts festival. This year's line-up includes Calvin Harris, Ellie Goulding, Ice Cube, Guns n' Roses, Of Monsters and Men and many others.
