Beyoncé and Mariah Carey pose backstage with their kids

By Sharnaz Shahid

Beyoncé joined another of the world's biggest pop stars, Mariah Carey, to show her support at the singer's All I Want for Christmas Is You concert on Sunday (Dec. 11) in New York. The vocal powerhouses were in high spirits backstage as they posed with their children.

Mariah, 46, took to her social media sites to share a snap, which was captioned: "Backstage at Christmas time with our beautiful children." The star, who was joined by her five-year-old twins, son Moroccan and daughter Monroe, looked typically glamourous in a plunging silver sequin gown, while Beyoncé kept things chic in an all-black ensemble. Beyoncé's four-year-old Blue Ivy — who was with a friend — looked cute as she posed with a large elaborate fan.

Earlier on in the evening, Mariah posted another snap in which she declared her love and admiration for the mother of one. She wrote, "love you @beyonce thank you sooooo much for coming out tonight!"

It's been a busy few weeks for Mariah thanks to her holiday concert. She also recently ended her relationship with Australian billionaire James Packer. And while she leads a busy life, the singer is very much the doting mother to her twins, who she shares with ex-husband Nick Canon.

The former couple were married for six years before filing for divorce in 2014. Still on good terms, they make sure their kids always come first, with Nick saying on the Ellen DeGeneres show last year: "We'll always be a family. We make the kids the number one priority, for them to see their parents together and for everybody to get along and have a good time."
