XTINA, A GREAT BIG WORLD RE-TEAM FOR AMAS

Christina Aguilera and A Great Big World will debut a new song at the American Music Awards on 11/24 and Post Malone will join forces with Ozzy Osbourne and Travis Scott while Green Day plays a couple of hits.

Based on Aguilera's Instagram post, it appears they will be doing a duet on the AGBW-penned "Fall on Me" that Andrea Bocelli recorded with his son Matteo last year.

Malone, nominated for seven AMAs this year, will deliver the world television premiere of “Take What You Want” with Ozzy, Scott and WATT. The new Aguilera and A Great Big World song is their first collab since 2013’s “Say Something,”which they perform six years ago on the AMAs.

Green Day will celebrate the 25th anniversary of Dookie with a performance of “Basket Case,” as well as their new single “Father of All…”.

They join previously announced performers Taylor Swift, Camila Cabello, Billie Eilish, Selena Gomez, Jonas Brothers, Kesha f/ Big Freedia, Dua Lipa, Lizzo, Thomas Rhett and Shania Twain.

The awards will be broadcast from the Microsoft Theater in Los Angeles on ABC.
