Christine and the Queens' cover of Beyoncé's 'Sorry' recently went down a treat with fans of both acts, and now the woman behind the name has lent her vocal talents to an even bigger and more well-known song.
Heloise Letissier joined none other than Elton John on stage at the Apple Music festival in London on Sunday night, singing and harmonising with him during 'Tiny Dancer'.
She also played her biggest hit 'Tilted' with John, who was later joined by several other guests on his own songs 'Bennie & the Jets', 'Goodbye Yellow Brick Road' and more.
John has previously talked about his admiration of Christine & the Queens, telling Beats 1: "I've been playing Christine and the Queens since last September, and she's finally broken England. I saw her at the Roundhouse in the Spring, and she was amazing ... Once you see her live on stage, you're mesmerised."
