His days of being a celebrity dog are behind him.

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

It was a real touch of class.

Kelly Clarkson and Brett Eldredge went "Under the Mistletoe" during the Christmas in Rockefeller Center special.

Tune into the special on NBC this December.

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

The unlikely combo blooms with emotion.

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

See if you can keep a dry eye.

'Sunday Drive' was released earlier this month, to critical acclaim.

"I was just praying I wouldn't turn on the radio one day and hear that song," he says.

This country hitmaker sure has a way with words.
