In 2016, Coldplay frontman Chris Martin brought his two kids, Apple and Moses, out for a performance at Glastonbury Festival. The kids joined him for a rendition of "Up & Up," which their mum Gwyneth Paltrow documented on Instagram.
Since then, the kids have lent their talents to their dad's music more than once. They were both featured on the song "Orphans" from Coldplay's 2019 album "Everyday Life," and Moses also sings on "Humankind" from 2021's "Music of the Spheres," while Apple is credited as a songwriter on the Selena Gomez duet "Let Somebody Go" from the same album.
Martin and ex-wife Paltrow welcomed Apple and Moses in 2004 and 2006, respectively.
