5 Seconds of Summer, Mary J. Blige and Sam Smith are the latest artists confirmed as performers for the 2014 American Music Awards. Those artists join the laready confirmed Charli XCX and second-time host and performer Pitbull on the show, which will broadcast live from the NOKIA Theatre L.A. LIVE on SUNDAY, NOVEMBER 23 (8:00-11:00 p.m., ET/PT) on ABC. Additional performers and presenters to be announced in the coming weeks.

Hailing from a small town in the western suburbs of Sydney, Australia, 5 Seconds of Summer blazed onto the scene and the charts with a collection of No. 1’s, including their U.S. debut on the Billboard 200 with their self-titled album. The pop-punk sensations sold out their first U.S. tour in less than five minutes and will embark on a worldwide headlining arena and amphitheater tour in 2015. In addition to taking to the stage at this year’s American Music Awards®, the band has the opportunity to walk away with a trophy, as they were nominated for “New Artist of the Year Presented by Kohl’s.”

Iconic Grammy Award-winning singer, songwriter, actress and philanthropist Mary J. Blige is a figure of inspiration, transformation and empowerment, making her one of the defining voices of the contemporary music era. With a track record of eight multi-platinum albums, nine Grammy Awards (plus a staggering 31 nominations), a 2012 Golden Globe nomination, and four American Music Awards, Blige is a global superstar. The singer/songwriter has attracted an intensely loyal fan base—responsible for propelling worldwide sales of more than 50 million albums. She will be on hand to perform her new single “Therapy” at this year’s American Music Awards ceremony. She is also in the running for “Favorite Female Artist – Soul/R&B”. Her new album “The London Sessions” will be released December 2 on Capitol Records.

British soul sensation Sam Smith will continue his breakout year with a performance of his hit single “I’m Not The Only One” on the American Music Awards® stage. His critically-lauded album, “In The Lonely Hour,” debuted at No. 1 in the UK and No. 2 on the Billboard 200 in the U.S., where it remained in the Top 10 for 13 weeks and shows no signs of slowing down. He is nominated for two awards – “New Artist of the Year Presented by Kohl’s” and “Favorite Male Artist – Pop/Rock” – giving Smith the chance to walk away with his first (and second) AMA trophy.

The 2014 nominations were announced earlier this month, revealing that Iggy Azalea is up for six awards–the most of any artist. Other top contenders include John Legend, Katy Perry and Pharrell Williams, who each earned five nominations and Lorde who earned four.
