American Idol has released a long list of guest stars for Sunday’s three-hour season finale.

They include Brandon Lake, the Goo Goo Dolls, Good Charlotte, Jennifer Holliday, Jessica Simpson, Josh Groban, Kirk Franklin, Myles Smith, Patti LaBelle and Salt-N-Pepa.

Typically, guest stars perform duets or group numbers with members of the Season 23 cast. And Idol typically invites the Top 12 or Top 14 back to perform.

No word yet on which contestants will perform with which guests stars.

Sunday’s show will also include performances by all three Idol judges — Lionel Richie, Luke Bryan and Carrie Underwood — and another by Seson 23 mentor, jelly Roll.

Of course, the main event will be a series of final performances from the Top 3 of Jamal Roberts, John Foster and Breanna Nix.

Be ready to vote early in Sunday’s episode. One member of the Top 3 is typically eliminated part way through the finale.
