Chris Martin and Gwyneth Paltrow may have “consciously uncoupled”, but they’re still collaborating as musicians – with Gwyneth singing on Coldplay’s new album.

The band’s frontman Chris asked his ex to sing on A Head Full Of Dreams, alongside three-year-old Blue Ivy Carter. Blue Ivy’s mum Beyonce, Noel Gallagher, and Tove Lo have all been previously announced as featured artists on the band’s forthcoming seventh album.

“Everyone who got asked to sing on our album has an important part in our lives,” Chris explained to The Wall Street Journal. “I don’t want to get too hippie, but what I’m trying to learn in my life is the value of every human. Inclusiveness is the key thing.”

He added: “The ‘choir’ started with my two kids coming in after school and recording. We recorded Blue Ivy Carter in New York when her mom Beyonce was in the studio. It comes from learning about Greek tragedy, where the chorus chimes in at times.

“To me, when we use that sound, it’s to affirm what I’m saying. ‘We agree with you, Chris. Keep singing’.”

Gwyneth appears on the song Everglow. Other songs feature a “choir” of children, friends and family members.

The rock band also teamed up with Stargate, the Norwegian dance pop producers behind hits like Rihanna’s Rude Boy, Katy Perry’s Firework and Beyonce’s Irreplaceable.

But it wasn’t a case of just hiring the duo, Tor Hermansen and Mikkel Eriksen. “I had to audition for them. They came over and I played a song for them on piano,” Chris said.

Coldplay’s album A Head Full Of Dreams will be released on December 4.
