The trio of stars join a packed line up of internationally recognised stars that are set to perform at the European Music Awards - held in the Mediolanum Forum in Milan, Italy, on October 25 - including Pharrell Williams, Ed Sheeran, Rudimental, Ellie Goulding and Jason Derulo.

American songstress Tori - who found fame on 'American Idol' - has been nominated for Best New Artist and Best Push and revealed the event will be the "highlight" of her year.

The 'Should've Been Us' singer shared: "Performing on the MTV EMAs will definitely be a big highlight of my year. I'm so excited to be a part of such an incredible show and thrilled to have a couple surprises."

However it's Taylor Swift who's tipped to be the big winner on the evening having been nominated for a whopping nine awards including Best Pop, Best Live Act, Best Female and Best Song for 'Bad Blood'.

And Justin Bieber will also be hoping to win big as he's shortlisted for Best Male and Best Pop as well as four others, while 'Thinking Out Loud' singer Ed and 'Orange is the New Black' actress Ruby Rose will take on hosting duties.

Voting for all award categories is open on mtvema.com until October 24.
