Watch Ariana Grande And Miley Cyrus Flirt And Sing In Onesies Together

Hey now.

Hey now -- Don't let your day start without watching Ariana Grande and Miley Cyrus dress up as a unicorn and a mouse and cover a Crowded House song. The two divas joined forces on a green, blow-up couch to sing "Don't Dream It's Over" for Miley's Backyard Sessions.

From the onesies to the flower-power plush pillows to the "flirting" to the adorable hug at the end -- everything about this video makes me want to squeal.

Miley has been collaborating with a number of artists to bring awareness to her Happy Hippie Foundation. Each video she releases on Facebook has a link to donate to the nonprofit organization, which provides support services to homeless youth. She's sung with Joan Jett and Laura Jane Grace, doing covers of The Replacements and Dido.
