He Houghs, He Puffs, He Screws Up His Neck

Derek Hough suffered a "Dancing" mishap this afternoon that did not involve his outfit or his Mystic Tan.

Hough, whose partner is the hot Shannon Elizabeth, wrenched his neck during the "Dancing with the Stars" rehearsal today and was taken to the hospital -- but we're told he's being a trooper (as in dance) and he went back to work.

No word if the neck injury involved a hickey.
