For an entire week in September 2017, Miley Cyrus appeared on every episode of The Tonight Show starring Jimmy Fallon to promote her brand new album, Younger Now.

She participated in games, musical performances, and interviews in each episode. On the Wednesday, October 4th episode, Cyrus and Fallon sang a duet that will have you doing a double take.

Paying tribute to Cyrus’ godmother, Dolly Parton, and her frequent duet partner Kenny Rogers, the duo sang “Islands in the Stream” dressed like the country legends.

Fallon first walked out on stage in a tuxedo, gray wig, and fake gray beard, looking eerily similar to The Gambler himself. Not long after Fallon’s entrance, Cyrus walked out, looking bustier than usual, wearing a gorgeous black dress with a sky-high blonde wig.

Not only did Cyrus and Fallon fit the part musically and with their outfits, but the set was also quite similar to one that Parton and Rogers performed back in the 1970s.

Dolly and Kenny released “Islands In The Stream” in 1983. It was written by the Bee Gees—Barry, Robin, and Maurice Gibb—and produced by Barry Gibb. The song was originally intended as an R&B song for Marvin Gaye, but it transformed into a country-pop masterpiece under the vocals of Kenny and Dolly. The track became a monumental hit, topping both the Billboard Hot 100 and the Country charts, and solidified the pair’s legendary status in the music world.

Rogers saw their performance, and absolutely approved of it, saying, “Jimmy Fallon and Miley Cyrus make a great duet…perhaps we’ll let them go on the road in place of us! I thoroughly enjoyed it.”
