Fiona Apple has kept a relatively low profile since her last album The Idler Wheel, which came out in 2012. But lately she's made her presence a bit more known, appearing at a Chris Cornell tribute concert and even confirming that she's working on new music. Now, she's gearing up to release her first new material of 2019, a collaboration with King Princess. The rising pop star shared the news on Twitter with a handful of collages teasing their collab. It's a major co-sign for the 20 year old singer, who's debut EP Make My Bed arrived just year. It's unclear just what the two have cooked up, be it a song or something else, but it's due out on Friday.
