Prince Harry and Coldplay frontman Chris Martin have been firm friends for well over a decade, with the Duke of Sussex even giving the Glastonbury superstar a shout-out in his 2023 memoir, Spare. They first made a public appearance together in 2014 when Chris, aged 47, penned a song for the inaugural Invictus Games. On a snapshot shared via Coldplay's Twitter account, Prince Harry, then 39, was seen in the recording studio with the band prior to the song's debut.
