Derek Hough & Bindi Irwin Recreate 'Dirty Dancing' Scene

Bindi Irwin and Derek Hough got soaked practicing their latest routine for "Dancing with the Stars."

If you can't tell by the picture ... they're recreating the famous Patrick Swayze and Jennifer Grey dance lift from "Dirty Dancing" for next week's movie night -- and seem to have already nailed it.

Bindi and Derek are already in the lead on the scoreboard ... and they're not going anywhere.
