With Chris Martin for their dad, it's no wonder that Apple and Moses Martin can hold a tune.
The Coldplay singer was joined by his children for a jam session in Malibu, and fans have been blown away by the youngsters' incredible vocals.
Clips from the low-key mini concert have surfaced on Instagram, showing Apple, 12, and ten-year-old Moses taking to the stage.
Apple sang Just a Little Bit of Your Heart by Ariana Grande
Apple, who was casual in a pink T-shirt and tracksuit bottoms, was the first to perform with her lookalike dad. She chose Just a Little Bit of Your Heart by Ariana Grande, showing she has the potential to be the music world's next pop princess.
Moses followed and wowed with his rendition of House of Gold by twenty one pilots. Chris, 39, accompanied his son on guitar but this time the Martins were joined by even more megastars – Beck, Red Hot Chilli Peppers drummer Chad Smith and Davide Rossi.

Chris, whose divorce from his wife Gwyneth Paltrow was finalised in July, was performing at a Malibu benefit gig for the Boys & Girls Club.
This isn't the first time that the singer has invited his young children on stage. Apple and Moses showed off their vocals at Glastonbury in June, when Coldplay headlined for a record fourth time.

The band performed a track by Viola Beach, the group who tragically died in a car accident in February.
Apple and Moses, and their two cousins, joined in on backing vocals and looked to be having the time of their life as they sang their hearts out in the tribute.
