They join a lineup that already includes Ariana Grande and Shawn Mendes.
The 2018 VMAs just got even bigger, as MTV just added two more performers to the mix.
According to a release, "Scott will debut his first solo performance with a medley of hits from his highly anticipated, chart-topping, recently released album, 'Astroworld,' and Malone will perform a song from his record-breaking album 'Beerbongs & Bentleys,' which debuted at No. 1 on the Billboard 200 Chart."
It was previously confirmed that Ariana Grande will perform "God Is a Woman" from her upcoming album during the show, her first live TV performance of the song.
While Tedder and Scott aren't up for any awards this year, the rest of the performers all earned multiple nominations. Ariana nabbed 5 noms, Shawn snatched up 3 and Logic and Post Malone are both up for 2.
Jennifer Lopez will also be honored with the "Michael Jackson Video Vanguard Award" and will perform for her first time at the award show since 2001.
The VMAs air live from Radio City Music Hall in NYC on Monday, August 20 at 9pm.
