It is not rare to see two stars collaborating on a project after their separation. One such example is of Coldplay's frontman Chris Martin and Gwyneth Paltrow. They are working together on an album.

According to the Wall Street Journal, Paltrow’s voice will feature on the track “Everglow,” a ballad about a relationship’s enduring spark. Chris’ current girlfriend Annabelle Wallis has also lend her voice to the album.

Moreover, Martin and Paltrow’s two children will also feature along with Jay Z and Beyonce’s three-year-old daughter, Blue Ivy. Martin said that they recorded Blue Ivy in New York and Beyonce was present in the Studio.

“Everyone who got asked to sing on our album has an important part in our lives,” Martin said.

Other key contributors include Noel Gallagher and Merry Clayton and Tove Lo.

The album titled, “A Head Full of Dreams,” is set to release on Dec. 4. Martin said that the inspiration behind the album is “Guest House,” a poem by a 13th century poet named Rumi that says, “Inclusiveness is the key thing.”

“A Head Full of Dreams” will be produced by Norweigan duo Tor Erik Hermansen and Mikkel Storleer Eriksen known as Stargate. The duo are known as the musical architects behind some hits of Rihanna, Lionel Richie and Owl City.

Martin and Paltrow married on Dec. 5, 2003 in Southern California, and in March 2014, the couple announced their separation after ten years of marriage, saying that the process is a “conscious uncoupling.” In April 2015, Paltrow officially filed for divorce.
