Elvis’s twin granddaughters hear his songs in stores. Priscilla says they have their own secret reaction.

An Elvis song comes on over the speakers at the store. Most shoppers keep pushing their carts and never think twice. But for two girls in the checkout line, that’s their grandfather singing.

Harper and Finley Lockwood are the twin daughters of Lisa Marie Presley, Elvis’s only child, and guitarist Michael Lockwood. They were born in October 2008 and turned 18 last month.

Their grandmother is Priscilla Presley, Elvis’s former wife. Back in September 2019, when the twins were 10, Priscilla gave Us Weekly a sweet update on how the girls handle being part of rock and roll’s most famous family.

That interview came just before Graceland’s first Elegant Southern Style Weekend, a celebration Priscilla hosted at the end of that month. She also sat down with a Memphis TV station around the same event, and it’s a chance to hear her talk about Elvis and her life in Memphis that same week.

Priscilla made it clear the girls know exactly who their grandfather is.

“I mean, they know, of course, who he is and they love his music,” she told Us Weekly. She said they’re “in awe” when they see how many people come to light candles at the yearly candlelight vigil at Graceland.

Even so, nobody in the family pushes Elvis on them. “It’s their choice on music. We don’t force and enforce,” Priscilla explained. “If they want to listen to Elvis music on Sirius XM radio, absolutely. If they want to listen to their own music, absolutely.”

So what happens when Grandpa’s voice suddenly fills a store? You might expect two kids to make a scene, or at least tell the people around them.

They don’t. “If they hear an [Elvis] song in a store, they’re very, um, demure about it,” Priscilla said. “They, you know, they will look at each other and look at us with little smiles.”

That’s all. A quick look between sisters, a little smile up at the grown-ups, and nobody else in the aisle has a clue who they are.

“So they’re very respectful,” she added.

Of course, Priscilla is a grandma, and she couldn’t resist a little bragging. “I can’t believe they are so smart [with technology],” she said. “I mean, they can handle the phone better than I can.”

She kept going, too. “They know how to Google already, they know how to draw things and characters, and oh, my gosh.”

She was also honest that 10 is young to take it all in. “I don’t know how much they can understand at 10 years old,” she said. In the end, she summed them up as simply as any grandmother would: “They’re just little girls experiencing life and having fun.”

Those little girls are young women now. Priscilla still shares rare photos of the twins in her own posts, and she marked their 18th birthday last month. Entertainment Tonight’s report on her birthday post is the easiest way to see them today.

It’s been seven years since that interview, and plenty has changed for Harper and Finley. Still, it’s nice to wonder if they still trade that same quiet look when one of Grandpa’s records comes on at the mall.
