Just a day after Miley Cyrus released her cover of John Lennon's "Happy Xmas (War Is Over)," she sang it beautifully on Saturday Night Live. The singer was accompanied by musician Mark Ronson and Sean Ono Lennon, who also worked with Cyrus on the song. Cyrus's soulful, raspy voice gives a welcome edge to this classic Christmas tune, and her high-energy performance totally gave me chills. She's been vocal about her plan to release a new album in 2019, and it's a treat to have new music already. Watch her impressive performance, get details on her festive Saint Laurent dress, and then listen to another one of her new songs, "Nothing Breaks Like a Heart" (if you don't already have it on repeat).
