If you’re looking for more star power on the X Factor, this week’s episodes are about to get a healthy injection. The show will welcome singers Justin Bieber, Nick Jonas, Will.I.Am, and Mark Anthony.

The artists will be paired with L.A. Reid, Demi Lovato, Britney Spears, and Simon Cowell respectively. They will join them at their home to judge contestants in their assigned category (to be announced). Each judge and guest mentor will then be making eliminations based on the home performances.

In the press release marking the news, Jonas was thrilled to have the chance to help contestants. “I’m lucky to have some incredible mentors in my life and I’ve always valued their opinions greatly,” he said. “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.”

Will.I.Am added that it was an easy ‘yes’ after being invited, and Mark Anthony said he was “really excited.”

The Judge’s Home episodes air this Wednesday and Thursday as well as next Wednesday. The live episodes of X Factor begin November 1.
