The singer performed the Blondie classic at the iHeartRadio Music Festival 2020 earlier this month to acclaim from fans, as well as the Debbie Harry, who said Cyrus “nailed it”.
UFC fighter Julian Marquez said if she dropped the cover on iTunes and streaming services, then it would be his “walkout song” on 14 November.
Following the release, Harry posted the link and praised the star once again, calling her version of the beloved 80s anthem “divine”.
Heart of Glass is Cyrus’ first release since the disco-tinged banger Midnight Sky, which has so far peaked at number one in Scotland, 10 in the UK and the top 20 in countries such as Australia, Canada, Ireland and the United States.
