Queen of Christmas Carey is back at No. 1 this week on the Billboard Hot 100 with her 1994 hit “All I Want for Christmas Is You”.

The musician’s daughter Monroe, 10, then sent her mom a sweet card that she’d written to celebrate the occasion, with the words “Congratz mama for the #1 for the billionth year” and “I love you Mommy, for-evah!” written on it.
