Gwyneth Paltrow and Blue Ivy Lent Their Voices to Coldplay's New Album

Coldplay's seventh studio album, A Head Full of Dreams, drops on Dec. 4, and there's already quite a bit of excitement surrounding the release. In addition to featuring some tracks that are out of the band's typical musical realm (one, for example, was inspired by Flo Rida's "Turn Down For What"), the album also includes some heavy-hitting celebrity cameos.

Lead singer Chris Martin recently spoke about A Head Full of Dreams with the Wall Street Journal, where he divulged that not only does Beyoncé sing on one of the tracks, but so does her daughter, Blue Ivy, as well as Martin's own two children and his ex-wife, Gwyneth Paltrow. "Everyone who got asked to sing on the album has an important part in our lives," Martin says. The album features a "choir" comprised of Apple and Moses, as well as others the band asked to croon. "The 'choir' started with my two kids coming in after school and recording," he says. "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.'"
