In an effort to get everyone feeling festive, Mariah enlisted her 7-year-old twins, Moroccan and Monroe, to help her belt out the hit song, 'All I Want For Christmas Is You'.

The 48-year-old singer took to Instagram to share with her 7.5 million followers a sweet video of herself belting out her 1994 classic with her little ones.

She wrote: "Roc & Roe have been practising 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!! 🎄🎶🎄🎶💖."

Donning their Christmas hats, it looks like Roc and Roe have inherited their mum's musical talent.
