Kelly Clarkson gave her fans a hump day they won't soon forget!

The songstress surprised a lucky group of people at The Grove Wednesday morning with an impromptu mini concert.

The new mama looked fabulous as she took to the stage in a green skirt, button-down blouse and retro-inspired shades for the outdoor performance.

Clarkson sang a plethora of her biggest hits, including "Since You've Been Gone" and her newest track, "Heartbeat Song."

And before she began belting out the opening of "Catch My Breath," she told the audience of kids and parents alike that they can "sing along if you know the words."

She quickly caught herself though, and joked that not everyone knows the lyrics to the 2012 single.

"I'm not even drinking yet," she told the overjoyed crowd. "'Yet' being the keyword!" Honesty is the best policy, right?

Clarkson has a jam-packed day ahead of her too, with another performance slated for tonight's episode of American Idol, where she'll also be mentoring the finalists.

Clarkson also performed in front of thousands this past weekend at the annual iHeartRadio Music Awards, where her adorable daughter River hung out backstage.

There's no rest for Clarkson!
