Happy Hippie Presents: Backyard Sessions - "Don't Dream It's Over" featuring Ariana Grande
Soooooo thankful for Ariana Grande for being a part of the #backyardsessions!! You're the sweetest little #happyhippie bear-mouse ever! Loooooove you The Happy Hippie Foundation #HappyHippiePresents #dontdreamitsoverPosted by Miley Cyrus on Thursday, May 14, 2015
Dressed in onesies -- Cyrus as unicorn and Grande as “mouse-bear” -- the duo sang the classic Crowded House number while sitting on an inflatable couch in Cyrus’ backyard.
As Cyrus puts it in the video, the duo gets momentarily distracted during their performance by a little “flirting.”
“Are you a mouse or a bear? Whatever you are, you're probably the cutest mouse-bear anyone's ever seen,” Cyrus says to Grande during the song’s interlude.
“You’re the cutest unicorn in the world,” the “Bang Bang” singer replies.
Since kicking off her Backyard Sessions performances earlier this month, Cyrus has performed with several stars, including rocker Joan Jett. These sessions promote Cyrus' newly-launched The Happy Hippie Foundation, an organization that supports LGBT and homeless youth.
“Soooooo thankful for Ariana Grande for being a part of the #backyardsessions!” Cyrus wrote on Facebook Thursday. “You're the sweetest little #happyhippie bear-mouse ever! Loooooove you.”
In an Instagram post addressed to Cyrus last week, Grande shared a similar sentiment.
“I can't thank you enough for doing something so important and for having me be part of something so special. Thank you for using your voice in such an incredibly positive and heathy way,” she wrote. “I love, appreciate and celebrate you.”
