(LOS ANGELES) -- The Dancing with the Stars judges will make room at their table Monday night for a familiar face.
Pro dancer Maksim Chmerkovskiy, who has not competed on the show this year, will join Carrie Ann Inaba, Len Goodman and Bruno Tonioli as a guest judge for the semifinals round.
Maksim's brother, Val Chmerkovskiy, who was partnered with the recently-eliminated Elizabeth Berkley Lauren, expects Maks to pull no punches. He says, "I guarantee you that he's going to steal the show. He'll be just as fair, and just as professional. But I'm sure he'll be a little bit less politically correct."
The five remaining couples must perform twice to the same song. First, they will attempt a jazz, paso doble, cha cha or tango routine to the "original" version of the song. Afterward, the teams will dance the Viennese waltz, Argentine tango or rumba to an "unplugged" rendition of the tune.
Corbin Bleu and his partner, Karina Smirnoff, will tackle the tango and rumba. Jack Osbourne is promising a performance with pro Cheryl Burke that will be even spicier.
"We're actually going to pull a page out of the Argentinean Dancing with the Stars and Cheryl will be getting naked this week. If you haven't seen that, YouTube it, go online and see it, it's the real deal," Osbourne said.
Dancing with the Stars airs at 8 p.m. Eastern time on ABC.
