Meet Luna, 7 year old rockstar extraordinaire and the surprise guest during Knocked Loose's performance of “Counting Worms.” This up-and-coming superstar stole the show as well as the hearts of Knocked Loose fans everywhere. 

“My bf and I are friends with the band and Bryan knows she loves their song 'Counting Worms'” says Luna's mom Stacie. “So he asked jokingly if she'd sing with him and she went for it. She's truly something else.”

We couldn't agree more. Check out Luna's stellar performance below.
