Ariana Grande and Miley Cyrus have been friends for years, cementing their mutual love in song with a cover of Crowded Houseâs âDonât Dream Itâs Overâ in 2015 for Mileyâs Happy Hippie Foundation. The two wore animal onesies, sang on a couch in Mileyâs backyard, and casually nailed the song. Itâs hard to re-create such a chilled-out, natural vibe in front of a crowd of thousands, but somehow, Ariana and Miley recaptured that energy once again at Arianaâs Manchester benefit on Sunday night. The two sat together onstage, hugged it out, and traded banter like the world wasnât watching. See their duet above.
