Gwyneth Paltrow, Blue Ivy and more lend voices to new Coldplay album

Chris Martin has rounded up an impressive roster of talent for the latest Coldplay album, running the gamut from ex-wife Gwyneth Paltrow, from whom he consciously uncoupled in 2014, to current girlfriend Annabelle Wallis. The frontman opened up to The Wall Street Journal about A Head Full of Dreams, which hits shelves on Dec. 4.

"Everyone who got asked to sing on our album has an important part in our lives," Chris said in the interview. "This is The Wall Street Journal, so I don't want to get too hippie, but what I'm trying to learn in my life is the value of every human."

Gwyneth, who split from the 38-year-old musician in March of 2014, lent her voice to the track “Everglow,” a ballad about the enduring spark of a relationship. Making it a family affair, the former couple's two children, Apple and Moses, are also featured on the album. Chris’s girlfriend, actress Annabelle, sings in a “choir” that is heard on multiple tracks.

“Inclusiveness is the key thing,” the Coldplay frontman said. “The 'choir' started with my two kids coming in after school and recording."

Another surprise guest on the group's new album is Beyoncé and Jay Z’s 3-year-old daughter, Blue Ivy. “We recorded Blue Ivy Carter in New York when her mom Beyoncé was in the studio,” Chris said.

Chris and Gwyneth divorced after 11 years of marriage after making a highly publicized announcement that they were “conscious uncoupling.” Asked whether or not the phrase would make a good future lyric, Chris admitted to the WSJ, “I don’t know. I didn’t invent that phrase, but I love it. Everything’s a good lyric if you have the right beat.”

The Gwyneth, 43, has previously spoken out about being friendly with her ex, saying at a conference earlier this year, "I think, unfortunately, though we couldn't stay in a romantic relationship, our values are very much around the importance of family and the importance of those relationships – and I'm lucky that we're aligned in that way."
