Idol Chatter & Voice Views

And promptly proved that she’s still capable of delivering magical moments for the show.

First, Kelly helped make the early portion of the show watchable with her self-deprecating sense of humor and her candid feedback as Idol’s Season 15 teeny boppers took the stage and struggled mightily to prove they are worthy of being the final Idol.

But the real magic came when Kelly took the stage and sang “Piece by Piece,” the title track from her latest album.

It’s a song about how Kelly’s father wasn’t around for most of her youth; her parents divorced when Kelly was 6.

And it’s a tribute to her husband, Brandon Blackstock, with whom Kelly has a daughter named River Rose and a son well on the way.

The reaction?

The YouTube video of the performance has been viewed nearly 1 million times in the last 24 hours.

And the song — released as a single in November — is sitting at number one on the iTunes singles chart.

Keith Urban was in tears during Kelly’s performance.

When she finished singing, the crowd began chanting “Kelly, Kelly, Kelly.”

“I figure you’re either crying at this performance or you need to check your pulse,” Keith told ETonline. “It’s an amazing song.”

Yep, and in the process, Kelly delivered her most important lesson of all to the Season 15 hopefuls — the power of singing something heartfelt.
