Ever met one of your heroes and felt as if your heart might explode?

Now you and Elle King have something in common.

The “Ex’s and Oh’s” singer, who appears with Dierks Bentley on his single “Different for Girls,” had the chance to meet the queen of her universe in Nashville recently-- and that would be the one and only Queen of Rockabilly, Wanda Jackson.

If you’re a fan of the two, it’s easy to see how they would love each other. They’re both pioneering female artists singing songs of love and heartbreak with just the right amount of sass, sensuality and honesty with grit-laced voices that would make the hardest of rockers green with envy.

It was mutual love at first listen and sight for King and Jackson.

Jackson surprises King over at the Fuselage boutique East Nashville, where an adorably nervous King gushes to Jackson, “You have the coolest voice I’ve ever heard.”

You know you have the ultimate seal of approval when Jackson tells you, “We’re soul sisters, aren’t we?”

The two then headed over to play some tunes together at the beloved Fanny’s House of Music, where Jackson recalled first hearing King’s voice.

“I was just flabbergasted," she said. "I thought ‘that sounds just like I did when I was twenty-something, you know?’”

So would they ever work on any music together? You’ll have to watch and find out.
