The 14-year-old daughter of Court, 54, and her ex-husband, David Arquette, 47, surprised her mother's Instagram followers when the Friends star shared this clip of the teen's very impressive vocals.
Coco performed Snow Patrol's Chasing Cars alongside the band's lead singer Gary Lightbody at a Chords 2 Cure benefit - and her famous mum couldn't have been prouder!
"I have overwhelming gratitude towards @garysnowpatrol for sharing his time to perform at @chords2cure. I just love watching Coco and Gary sing together," Courteney wrote alongside the Instagram post.
David got in on the action too, sharing his own Instagram video of his eldest child belting out Marvin Gaye and Tammi Terrell's Motown hit Ain't No Mountain High Enough.
"Oh my Gawd! I love you Coco Arquette... Brilliant," he wrote alongside the post.
Perhaps Coco got some pointers from one of Snow Patrol's other members, Court's fiance Johnny McDaid!
