WATCH: Miley Cyrus flirts with Ariana Grande in Don’t Dream it’s Over cover

Miley Cyrus invited pint-sized singer Ariana Grande to perform with her this week, as part of her Happy Hippie foundation’s backyard sessions to raise awareness for homeless and LGBT youth.

The pair, who are dressed in onesie pajamas, covered Crowded House’s hit Don’t Dream it’s Over - and it’s simply stunning.

During the song Cyrus gets momentarily distracted by a little flirting with “the cutest mouse/bear anyone’s ever seen”, Ariana.

“You’re the cutest unicorn in the world,” the Bang Bang singer replies.

This causes the singers to blush and mess up the second half of the song.

“Sorry, I was flirting,” Miley says, apologising to the band.
