Lady A have been regular performers at CMA Country Christmas over the years. This year, not only will they be performing during the show, they will also be hosting it.

Christmas has always been very important time of the year to them, but this year it will be extra special. After Charles Kelley announcement in September that he'd been diagnosed with a rare form of blood cancer called multiple myeloma, he said he was hoping to continue working as much as possible while undergoing treatment and it looks like he's going to be able to do that.

A month after announcing his diagnosis, he told fans that his cancer treatments were working the way doctors hoped they would — but that he'd underestimated just how tough the side effects would be.

CMA Country Christmas airs December 1st at 9pm on ABC. Other performers for the night include Dan + Shay, Jordan Davis, Russell Dickerson, Trisha Yearwood and more.
