Kelly Clarkson sings 'Since U Been Gone' backwards for Jimmy Fallon

After all, Im a professional, she told Jimmy Fallon onThe Tonight ShowTuesday night.

So the host challenged her to prove it.

Inspired by YouTube videos, Fallon asked Clarkson to perform her 2004 hit song Since U Been Gone backwards.

At least she had Fallon as her hype man.

The late-night host was seen head-banging hard when Clarkson got to the refrain.

Elsewhere on the show, she got her chance to perform one of her songs the traditional way.

Watch her sing Whole Lotta Woman, off her new album,Meaning of Life, below.

We have four children that can be very taxing with a schedule.

It was just a no-brainer for me withThe Voicebecause of that alone.

But my thing is, I was kind of bummed too when [Idol] came to me.

I hope its super successful.
