When you're the legend who brought "All I Want For Christmas Is You" to life, it's pretty safe to say your kids will grow up listening to the iconic song — a lot. Mariah Carey can attest to that, and this year, her adorable twins are helping her out with vocals! Mariah shared a video on Wednesday of her 7-year-olds, son Moroccan and daughter Monroe, singing along in the car while were both decked out in Santa hats.
"Roc & Roe have been practicing the background vocals to 'All I Want For Christmas Is You,'" Mariah wrote in her caption. "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!!" Watch it above, and then prepare to play the song on repeat.
