Coldplay obviously do not receive daily coverage here at HNHH, but when we find out the band has two of hip-hop royalty on their upcoming album, we can't help but alert you guys.

Chris Martin, the band's lead singer, and ex-husband of Gwenyth Paltrow, is already known to be friends with power couple Jay Z and Beyonce. So perhaps it's not so surprising that their well-established friendship would lead to a musical collaboration. During a new interview with the Wall Street Journal, Martin revealed that not only does Beyonce make an appearance on a record called "Hymn for the Weekend," but Blue Ivy has vocals through out A Head Full of Dreams.

The album contains a "choir" on various records, which consists of some of the band's close friends, family and children. Martin says, "The “choir” started with my two kids coming in after school and recording. We recorded Blue Ivy Carter in New York when her mom Beyoncé 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."

He also notes, "Everyone who got asked to sing on our album has an important part in our lives."

A Head Full of Dreams is out on December 4th.
