Mariah Carey has found a new pair of pint-sized back-up singers, and she didn’t have to do much to recruit them.

Their names are Moroccan and Monroe – her 7-year-old twins – and they helped mom out on her own holiday classic, “All I Want for Christmas Is You” – Carpool Karaoke-style.

The most downloaded holiday single of all time is blaring from the speakers as Carey encourages the twins to sing the backing vocals at the appropriate times.

Mariah tweeted the adorable results with the caption: “Roc & Roe have been practicing the background vocals to “All I Want For Christmas Is You”, we’re gonna take this one step at a time – we’re very excited about it! It’s our first video doing this! It’s festive, Cmon!
