Lorde Confirms Ariana Grande's 'Mockingjay' Track, Reveals The Title

Get ready for Major Lazer and Ariana's 'All My Love.'

Arianators, assemble! Ariana Grande is now absolutely, 100% confirmed to make an appearance on the soundtrack for "The Hunger Games: Mockingjay -- Pt. 1."

Lorde, the album's curator, tweeted that the "Love Me Harder" singer's "angel pipes" will be featured on track #5: "All My Love" by Diplo's side project, Major Lazer.

Grande retweeted Lorde's confirmation, and added a message all her own about "All My Love."

Ariana first teased the new song during an intimate, at-home livestream for fans last week, saying: "It's a very interesting song. It's very different."

When Lorde originally released the "Mockingjay" track listing, which features heavy-hitters like Kanye West, Haim, Pusha T and Charli XCX, the 17-year-old singer/songwriter left a mystery "track 5" unnamed, later explaining: "it's just not quite finished."

The soundtrack is due out November 17, with "The Hunger Games: Mockingjay - Part 1" hitting theaters November 21.
