The 47-year-old "Mariah's World" star and her 5-year-old twins, Monroe and Moroccan, snapped a photo backstage with Beyonce and her 4-year-old daughter, Blue Ivy, following Carey's holiday concert Sunday.
"Backstage at Christmas time with our beautiful children. @beyonce #christmas #family #love," Carey captioned the group picture Monday.
Carey kicked off her third annual All I Want for Christmas is You concert series Dec. 5 at Beacon Theatre in New York, and will perform through Dec. 17. She had shared a selfie with Beyonce from the show on Sunday.
"I love you @beyonce thank you sooooo much for coming out tonight! #merrychristmas," she wrote.
Carey shares her kids with ex-husband Nick Cannon, from whom she split in 2014. The singer said in an interview with E! News in August that Cannon and their twins have enjoyed filming her E! series, Mariah's World.
"It's fun for them. They want to be around it," she said of Monroe and Moroccan. "They're so funny that they should have their own show. They're twins and and they have, like, their own little language and it's hilarious."
"It was nice because we did have their father and he came and did a moment," the star revealed. "We try to keep it, the co-parenting, so the kids can feel good about things like that and not feel like it's any weirdness or anything."
Carey last released the album Me. I Am Mariah... The Elusive Chanteuse in 2014, while Beyonce released Lemonade in April. Beyonce is nominated for nine awards at the 2017 Grammy Awards, including Album of the Year.
