Playing Watch Miley Cyrus and Ariana Grande Flirt During Flawless Cover of 'Don't Dream It's Over'

They may be inΒ ridiculousΒ onesies and sitting on an inflatable couch, but Ariana Grande and Miley Cyrus are seriously singing in this latest edition of Happy Hippie Presents: Backyard Sessions.

The pop stars cover Crowded House's 1986 hit, "Don't Dream It's Over," and their voices seem made for each other. Cyrus, 22, and Grande, 21, recorded the song with a band in the former Hannah Montana star's own backyard (hence the name of the sessions).

During the track's musical interlude, Cyrus asks Grande, "Are you a mouse or a bear? Whatever you are, you're probably the cutest mouse-bear anyone's ever seen."

Grande responds, "You're the cutest unicorn in the world."

The compliments cause the girls to miss their cue, leaving Cyrus to apologize: "I was flirting. Sorry!"

Grande also gushed over Cyrus via Instagram and showed support for her charity, The Happy Hippie Foundation, which rallies "young people to fight injustice facing homeless youth, LGBT youth and other vulnerable populations."

"I can't thank you enough for doing something so important and for having me be part of something so special," she posted along with a pic from the backyard session. "Thank you for using your voice in such an incredibly positive and healthy (sic) way. ...I love, appreciate and celebrate you."

When she's not all covered up in a unicorn onesie, Cyrus is hitting the stage in pasties. That was the case when she performed at the Adult Swim Upfront Party in New York City on Wednesday. Cyrus paired her pasties with huge butterfly wings and latex leggings, leaving her hard to miss at the event.Β

She also lit a fat cigar while on stage.

Prior to her flirtatious banter with Grande and the scantily-clad stage show, Cyrus opened up about her sexuality during a Facebook Q&A. "I never want to label myself!" she said. "I am ready to love anyone that loves me for who I am! I am open!"
