Miley Cyrus gave a stunning performance of her new song "Nothing Breaks Like a Heart" on Saturday Night Live. She and Mark Ronson, who produced the song, were this week's musical guests for a hilarious episode hosted by Matt Damon. We already got a taste of a more stripped-down version of Cyrus's catchy song when she and Mark shared an acoustic version. The musical duo teamed up for more songs that Cyrus will include on her next album, which she promises will definitely be out in 2019. Watch the live performance above, get details on her jaw-dropping Gucci tracksuit, and then listen to the talented pair's cover of a classic Christmas song.
