Bindi Irwin and Derek Hough may have just done the best routine of the entire "Dancing With the Stars" season with their homage to "Dirty Dancing" Monday (Oct. 19).

What made it so epic? Well, first off -- former "DWTS" winner Jennifer Grey showed up to give them some tips.

"You're more of who Baby is than I was," the star of the 1987 film tells Irwin. "The key is to trust."

The iconic lift move definitely gave them both some nerves, as Hough says it was the most nervous he's ever been on "Dancing With the Stars." But they absolutely nailed it.

Not only that, but they had so many recognizable moments from "Dirty Dancing" that it was a feast for fans of the movie. The judges were huge fans.

"Your legs were on fire, gorgeous, gorgeous," says Julianne Hough. "The dynamics and the details that are in this dance, those little things that are in the movie in that particular dance ... you guys had every little detail."

"You both were amazing, absolutely incredible. Really touched my heart, enchanting job," adds guest judge Olivia Newton-John.

Bruno Tonioli says that Irwin is his "little star" who has gone "supernova" with this dance, calling it "blindingly brilliant in both execution and interpretation."

Carrie Ann Inaba says that when Irwin dances like that, it makes the judges' job easy -- and they all give her 10s for a perfect 40.
