Chris Martin and Gwyneth Paltrow continue to prove that they remain amicable even after their divorce.

Case in point: Martin's ex-wife even appears on his upcoming Coldplay album, A Head Full of Dreams, along with his new girlfriend, Annabelle Wallis.

When asked about why he chose to have both past and current loves become part of the album, the band's frontman tells The Wall Street Journal, "Everyone who got asked to sing on our album has an important part in our lives. 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."
