At first she thinks it’s cheering, but it’s not a fan has passed out.

She quickly requests a medic.

But even before that uneasy moment, Clarkson has been hitting pause for reasons of her own.

“I’m sorry, y’all,” she tells the crowd.

“I love that territory.

“I also have to use humor as a healing mechanism, a coping mechanism.

I do that all the time.

So I was writing a love song and I was just angry.

I was like, ‘God, why are you still so into something that was so bad?'”

Her response was especially surprising to her given that the show’s two nights of rehearsals were tear-free.

“It was pretty flawless and easy and great,” she says.

“I was almost proud of myself.

And then all of a sudden it was just like a wave washed over me.”

It wasn’t, of course, the first time she felt it.

But Clarkson isn’t worried about comparisons.

That’s the worst feeling ever.”

Full separation isn’t an option.

“That’s just going to take time which is annoying.

I don’t like that,” she admits.

“I will sing ‘Because of You’ and still remember why I wrote it at 16.

It took time for me with ‘Piece by Piece,’ with ‘Hazel Eyes.’

You dive in, but you’re treading water.”

I don’t have control over it.

You have to learn to let that go and live in the moment, whatever it is."

With this one, she wants the crowd to know that mama got her groove back.
