Miley Cyrus [1] is going back to her roots. On Friday, the singer dropped the music video for her new single, "Younger Now [2]," and it's full of nostalgia. Not only does she sing along with a puppet version of her younger self (yes, really), but she also impersonates one of her idols, Elvis Presley, who passed away 40 years ago this month [3]. Aside from jamming out on the guitar and kissing an older woman, she also seems to poke fun at her Hannah Montana days by doing a hoedown-inspired dance in a 1950s sock-hop setting. Needless to say, we can't wait to see what the rest of her album will sound like!
