American Idol finalists Phillip Phillips and Jessica Sanchez

*Tonight’s “American Idol” season 11 finale will feature all-star musical tributes to the late Donna Summer and Robin Gibb.

Helping the contestants translate Summer’s classic songbook (the disco queen appeared on the season 7 finale) will be a group performance with ’70s icons Gloria Gaynor, Thelma Houston and Gladys Knight joined by Nelly Furtado, Sheila E., Jennifer Holliday and, of course, the Season 11 girls (later in the show, they perform with Chaka Khan).

In addition, Broadway and “Glee” star Kristin Chenoweth will trade vocals with finalist Jessica Sanchez on the Summer-Barbra Streisand girl power anthem, “Enough is Enough.”

Among the other stars set to perform with the finalists are John Fogerty, who will duet with Phillip Phillips, Reba McEntire, who will kick up her boots with Skylar Laine and the long-awaited Fantasia-Mantasia mash-up for second runner-up Joshua Ledet.

Sanchez will join “Dreamgirls” soul-mate Holliday for an encore performance of “And I Am Telling You I’m Not Going,” and the boys will sing with Neil Diamond for yet another group number.

Latin superstars Wisin and Yendel will salsa with touring partner and “Idol” judge Jennifer Lopez, while Hollie Cavanagh will team with Season 6 winner Jordin Sparks for a Broadway show tune.

Previously announced performers include hitmaker Rihanna and rockers Aerosmith.

The season finale airs tonight from 8 to 10:07 p.m. on FOX.
