Nov. 29 (UPI) -- Mariah Carey uploaded onto Twitter a video of herself and her twin children Monroe and Moroccan singing "All I Want for Christmas Is You" together.
The clip, released Wednesday, was filmed while the family was traveling together in a car. Monroe and Moroccan, both 7, act as backup singers for Carey before joining in to perform the song's chorus.
"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!" Carey captioned the video.
"All I Want For Christmas Is You," is Carey's signature holiday hit. The song is the most downloaded holiday single of all time and the 11th-highest-selling single ever.

Carey also made headlines on Wednesday for once again commenting on her rumored feud with Jennifer Lopez.
The singer, who famously said "I don't know her," when asked about Lopez in the 2000s, said in an interview with Pitchfork that she was trying to be nice.
"I really was trying to say something nice or say nothing at all. I really was," she said.
