"Gangnam Style" invaded "Dancing with the Stars" last night -- and the result was a "hot mess."
The group routine involved nearly-naked Gilles Marini, shirtless Val Chmerkovskiy, Cheryl Burke riding Emmitt Smith, confetti and some extreme Kirstie Alley booty-shaking.
And somehow, it got a standing ovation.
The number, set to PSY's massive hit, was one of the strangest to ever hit the stage on the ABC reality show ... but the judges loved it.
"It wasn't tight, it wasn't together ... it was fun," Len Goodman proclaimed, while Carrie Ann Inaba said "sometimes hot mess is excusable and turns into crazy fun insanity."
The group was given a 27 our of possible 30.
