Justin Bieber and his manager Scooter Braun will partner LA Reid, with Marc Anthony joining Simon Cowell and Nick Jonas teaming up with Demi Lovato. Pictures of all three judging teams on location have been released by Fox.
Additionally, Britney Spears is to be joined by will.i.am for Judges' Houses, and the Black Eyed Peas musician praised the quality of talent among the show's final 24 contestants.
"When Britney asked me to come help mentor talent in the Judges' Homes round, it was an easy yes," the Voice UK coach said. "Some of the talent I've seen so far has blown me away - they're out-of-this-world good."
Jonas said: "I'm lucky to have some incredible mentors in my life and I've always valued their opinions greatly. Being able to provide guidance for another artist, while working with the incredibly talented X Factor team, was an amazing experience.
"There's some extraordinary talent out there, and I couldn't be more thrilled to be a part of their journey."
Anthony said that he feels "really excited" by acting as a mentor to X Factor contestants, adding that he is "looking forward to seeing them advance in the show's new season".
The X Factor USA's Top 24 contestants will be revealed tomorrow (Wednesday, October 10) at 8/7c on Fox.
