The Kelly Show??

On The Ellen DeGeneres Show Thursday, Ellen allowed guest Kelly Clarkson to take over as host as preparation for her upcoming gig hosting the Billboard Music Awards.

Kelly got her own desk, her own coffee mug and even her own theme sequence using her hit “Heartbeat Song.” She welcomed Ellen as her first guest and asked her a couple of questions, starting with, “If you had to pick your favorite person that’s ever come on this show, who would it be?”

Ellen then rattles off a bunch of names including Pink, Alicia Keys and Chris Hemsworth – but not Kelly, prompting her to exclaim, “SERIOUSLY?”

The two also participated in a bit on The Kelly Show called “Kelly’s Karaoke,” where they sang a duet of Kelly’s hit, “Since U Been Gone.”
