Earlier this month Lionsgate confirmed the track-listings for the soundtrack to ‘The Hunger Games: Mockingjay pt. 1’ but left out one track in the announcement. That track was track five, and now it has now been confirmed as one of Ariana Grande’s latest songs.

Lorde curated the soundtrack for the highly-anticipated film, now according to Grande, who confirmed her involvement during a live stream last night, the song will be “interesting” and “very different” collaboration between herself, Lorde, and Diplo.

Th always pony-tailed songstress wouldn’t give-up the song’s title, and we still don’t have an exact sampling of the track, but you can bet it will be a favorite among her fans. The Hunger Games: Mockingjay – Part 1 was directed by Francis Lawrence and stars Academy Award winner Jennifer Lawrence, Josh Hutcherson, Liam Hemsworth and Woody Harrelson. The film is the latest installment in Lionsgate’s global box office phenomenon based on Suzanne Collins’ bestselling “Hunger Games” trilogy and will be released in theaters worldwide on November 21, 2014.
