Miley Cyrus dropped her "Younger Now" music video Friday, and it's retro throwback to the sock-hoppin' '50s.

The four-minute video (above) features the pop star singing and dancing alongside young kids and senior citizens, while dressed in outfits inspired by the era's biggest star, Elvis Presley -- just in time for the 40-year anniversary of the rock 'n' roll icon's death this week.

Cyrus told Billboard in May that she came up with the title track of her new album after she had a conversation with her mother, Tish Cyrus.

"She was like, 'I swear to God, you are younger now at 24 than you were at 4!' And so it just hit me, like I am f-cking younger now, and I am proud of that," she said.

Another fun fact about the new music video: It was co-directed by Cyrus, alongside Diane Martel.

Her album, "Younger Now," drops on Sept. 29.
