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!”
