Mariah Carey's beautiful kids show off their voices while singing an iconic Christmas song

Mariah Carey shared a sweet video on Instagram featuring her children as they sang the backup vocals of her Christmas classic hit.

The singer may have discovered her new backup singers – her seven-year-old twins Moroccan and Monroe.

Carey beamed with pride at their bonding moment as they sang Carey’s “All I Want for Christmas Is You,” while they were riding in a car.

Jamming together, it was clear that the twins had been blessed with Carey’s talent in singing.

Carey wrote on 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!"

She added, "It's our first video doing this! It's festive, Cmon!!"

The trio was singing the backup vocals of the song as it played loudly on speakers. Carey coached her son and daughter throughout the video, and the twins appeared to be really into it.

They were even making gestures and seemed comfortable in front of the camera. We might be expecting budding singing careers for the two in the future.

With how adorable the twins were in the video, Carey’s fans couldn’t help but gush over them in the comments.

The singer shares Moroccan and Monroe with actor and comedian Nick Cannon. The pair tied the knot in 2008 after meeting on the set of Carey’s music video for “Bye Bye.” They welcomed the twins in 2011.

By 2014, the pair announced that they were officially separated and the divorce was not finalized until 2016. It was on that year that Carey was engaged to James Packer, an Australian billionaire. Although, they broke off their engagement by October on that same year.

Even though Carey and Cannon have been divorced, they still maintain a cohesive relationship as they co-parent the twins.

In an interview with Entertainment Tonight in April 2018, Cannon shared that they still talk every day. He also opened up about Carey’s bipolar disorder and said that he was “in awe of her strength.”

Meanwhile, Carey finally addressed the rumors that she and Jennifer Lopez are feuding. The speculation started when Carey expressed that she was not familiar with Lopez even though they have both been top-rated artists for years.

Carey clarified that she wasn't being shady at all and she meant no harm when she said that she didn’t know who Lopez was. In 2016, she said to TMZ, “I still don’t know her!”
