Kelly Clarkson

"It's just a difficult thing," she admits.

These country artists have all taken the stage during the NFL's biggest game of the year.

On a recent episode of 'The Kelly Clarkson Show', the two artists finally met -- and they performed their new holiday duet, too.

She was really struggling with how to define the feelings that come with the end of a marriage.

It was a real touch of class.

Clarkson took on a Billy Currington classic for her latest 'Kellyoke' installment on 'The Kelly Clarkson Show.'

The upbeat, festive love song, penned by Clarkson, arrived on Wednesday (Oct. 28), just under two months out from the year-end holiday.

"I think that might be illegal!" she admits.

Both singers have now been through very public divorces.

They live in a way that most people can only imagine.

Kelly enlisted the country Christmas crooner himself — Brett Eldredge — for this original duet.

You'll have to wait just a little longer for Blake Shelton and Gwen Stefani to return to television.
