There were some gasps when host Brooke Burke revealed Maks would be the guest judge right before his ex GF, Karina Smirnoff, performed with partner Corbin Bleu.
The two danced a perfect scoring rumba that ended with an unexpected kiss. Chmerkovskiy praised Smirnoff for being "one of the top five female dancers in the competition," which led the pro dancer to lean over the judges’ table and give her ex a friendly peck.
As for Remini’s departure, she said, "I take away so much. I have to thank Tony. He's put in so much work ... This has been an amazing experience ... Everybody has been amazing."
Dovolani added, "I've never looked so forward to practices every single day. This was an incredible experience. If every season is like this, I will be living a very long life."
Tune in to “DWTS” next Monday to see who will be the final three!
