Gwyneth Paltrow watches Coldplay headline Glastonbury

Paltrow and Chris Martin's children Apple and Moses also provided vocals on 'Up & Up'

Gwyneth Paltrow watched Coldplay headline Glastonbury.

The band, who are led by Paltrow’s ex-husband Chris Martin, were the festival’s final headliner, performing on the Pyramid Stage tonight (June 26).

The actress was spotted taking photos and filming during ‘Up & Up’, on which the former couple’s children Apple and Moses took to the stage to sing with their father.

At one point during the set, Martin was forced to play solo due to technical issues.

While playing ‘Everglow’, Martin halted the band to ask about an issue with his piano’s tuning.

“Wait, wait, wait, what’s going on there, man? Is that really out of tune?” he asked his bandmates. “One of us is out.

“That’s a terrible problem,” he continued. “Shall we just skip to the next song or should I just do it on my own?”

The crowd booed at the suggestion of missing the song, to which Martin responded: “OK, so having introduced the best band of my lifetime, now they’re going to leave me on my own, but we can muster through.”

He then played the rest of the song by himself, before the band were reintroduced for the next track, ‘Clocks’.
