It's tiiiiiiiiiiiiiiiime! That's right, the queen of Christmas herself, Mariah Carey, has defrosted and is ready to celebrate the holiday seaso n with us (although let's be real, most of us have been blasting "All I Want for Christmas is You" the second November 1 rolled around).

The acclaimed Grammy-winning singer appeared on "The Jennifer Hudson Show" as she promotes her ongoing Christmas concert tour.

Her voice is still strong and powerful. She hit her signature whistle notes throughout the night, including at the end of “Oh Santa!”

The song dashes from No. 3 to No. 1 on the former and 8-1 on the latter. ‘Tis the season for other holiday hits in the charts' top 10, as well, led by Wham!'s "Last Christmas," which leaps 9-2 on the Global 200 and returns to the Global Excl.

The icon is back in the holiday spirit and bringing it on a nationwide tour: "Last year wasn't my most fun version of Christmas ever, so ... come hell or high water, we're going to have fun!"
