Chris Martin is known for being the frontman of Coldplay, who are one of the biggest British rock bands of all time.
The group are currently on their Music of the Spheres world tour and the 46-year-old Yellow singer shocked fans when he arrived in Cardiff via train on Tuesday ahead of their two nights of gigs at the Principality Stadium.
The father-of-two, who is known for being a very humble popstar, brought a fan up on stage on the first night after spotting his emotional poster in the crowds and sang Everglow with him in honour of the man's friend, who had passed away.
