The Aussie pop-punk band joins Sam Smith and Mary J. Blige as confirmed performers for next month's broadcast, announced on the AMAs Facebook page Thursday.

Smith is up for male pop/rock artist and will also compete with 5 Seconds for new artist. Although not a nominee, Blige's The London Sessions album (which features Smith) is out Dec. 2.

Pitbull will host the show, broadcast live from the NOKIA Theatre L.A. LIVE on Nov. 23 at 8 p.m. ET/PT on ABC. Iggy Azalea leads the nominations with six, including artist and single of the year.
