Gwyneth Paltrow and Chris Martin are the friendliest exes ever!

The exes are so amicable that the Colplay frontman's former wife is featured on the bands upcoming album, A Head Full of Dreams.

Paltrow makes an appearance on "Everglow," a song that is reportedly about "a relationship's enduring spark," according to The Wall Street Journal.

Martin sat down with the publication, where he opened up about the couple's "conscious uncoupling" back in 2014.

"I didn’t invent that phrase, but I love it," said Martin on whether the now infamous term would make a good song lyric. "Everything’s a good lyric if you have the right beat."

Last week, the band debuted the album art to their newest record on Instagram, and also revealed that it will drop on Dec. 4.

Paltrow isn't the only featured guest on the band's new album. Not only does Beyonce have a guest spot, but her 3-year-old daughter, Blue Ivy, does too!

"We recorded Blue Ivy Carter in New York when her mom Beyoncé was in the studio," said Martin.

"Everyone who got asked to sing on our album has an important part in our lives," the singer explains, adding, "What I’m trying to learn in my life is the value of every human."

Paltrow and Martin divorced in 2014 and have a daughter, Apple, and a son, Moses. The former couple seem to have remained friends long after their split. Last week, Martin opened up about his new outlook on life following the breakup.

"Those two things started me off on this whole journey where I just feel so happy to be alive," he said to Australia's 2DayFM's Rove and Sam. "That may sound a little simple but I suddenly feel very grateful to be alive. If it's coming across then that's great to hear."

The outlook definitely comes across, as ET obtained pics of the two celebrating Paltrow's 43rd birthday in September. The friendly exes were spotted hugging, with Paltrow even giving Martin an affectionate kiss on the cheek. And earlier this month, Paltrow was spotted dancing along to Coldplay’s intimate set at a Downtown L.A. show

Paltrow did admit, however, that their relationship is "definitely imperfect."

"It's been hard, and we've gone through really difficult times, but we've always said these children are our priority," Gwyneth said in July. "What that really means is even though today you hate me and you never want to see me again, we're going to brunch because it's Sunday and that's what we're going to do."
