The holiday season is one of the busiest for award-winning singer Mariah Carey as she performs at multiple Christmas shows all inside and outside the United States.

Something very sweet happened at one of her sold-out Christmas shows in Toronto, and our hearts are melting at this heartwarming gesture.

Keep reading for the details.

Mommy And Daughter Moment

The star welcome daughter Monroe to the stage for a Christmas Duet as they performed Away in a Manger together in front of hundreds of audiences.

The pair looked divine in dazzling white dresses and tiaras as they shut the stage down at the Scotiabank Arena on Friday night and harmonized on some major whistle notes.

"Eleven years ago, I got the greatest gift," Carey told the audience as she introduced her teenage daughter. "I don't have birthdays, but the birthing day was the greatest gift ever when I had my twins, Roc and Roe."

Monroe And Moroccan Joined Carey On Stage Last Month

While this is Monroe's first-ever duet with mom, the twins recently joined their mom for an All I Want For Christmas is You performance at the Macy's Thanksgiving Day Parade.

The singer introduced her children to the crowd in a dramatic manner as they came out of the gift box, which burst open midway into her performance and then danced alongside her for the rest of the song.

She looked incredible in a crystallized umbrella, a bejeweled crown, and a pink floor-length gown as toy soldiers danced around her.

Booked And Busy

The unofficial "Queen of Christmas" also performed at Madison Square Garden, New York, on December 13 for her Merry Christmas to All holiday shows.

Another two-hour TV holiday special of the same title aired on CBS on December 20, which featured her performance of her festive hits, including the monster hit and annual favorite All I Want For Christmas is You.

Not to forget that this same song raked in a whopping $50 million in royalties between its release in 1994 to 2013 according to a New York Post article in 2014.

The singer recently lost a trademark case which won't see her officially being called the Queen of Christmas anytime soon. The United States Trademark Trial and Appeal Board recently ruled that the award-winning singer and songwriter can't claim ownership of the title.

Wondering why? well, Elizabeth Chan, a full-time Christmas recording artist has formally blocked Carey's move to trademark the title on top of Carey's further attempts to register trademarks for "Princess Christmas" and "QOC"
