Former “Little House” cutie turned Screen Actors Guild president Melissa Gilbert is this year’s chosen star, heading to the ER after, reportedly hitting her head on the dance floor during her paso doble with professional partner Maksim Chmerkovskiy on Monday, though Maks insisted to Web site TMZ she’d merely “bumped her head.”

“If you’re wondering why Melissa and Maks are not here, she injured herself” and has been taken to the hospital, WaPo TeamTV “Dancing” correspondent Emily Yahr reported the show’s host Tom Bergeron explaining in the final seconds of Monday’s broadcast.

“Concussion” AND “whiplash,” Gilbert had tweeted proudly a while later. Shortly thereafter, she added, “@GavinDeGraw bless your heart for carrying me down those stairs!”

It was another of the show’s pro dancers, Karina Smirnoff, who told a gaggle of press assigned to cover “Dancing” from backstage, that Gilbert said she had hit her head on the floor during her performance.

Gilbert, 47, has not suffered silently through this season of “Dancing.” In the most recent post for a Monday “Dancing” blog she’s been writing for People magazine, Gilbert whined: “ I have a burn on my ankle from being dragged across the floor by Maks. It will scar. No question. The scar is mine. I earned it by working really hard.”

Two weeks earlier, she’d blogged, in re the quickstep: “this is one of the most vexing, frustrating things I have ever asked my body to do. Childbirth is easier.”

Gilbert joins a long “Dancing With the Stars” injured list. In fall of ’09, Former House Majority Leader Tom DeLay had to drop out of the competition after breaking bones both his feet. In the spring of ‘11, pro dancer Kym Johnson was clearly seen being dropped on her head during rehearsal with her celebrity partner, NFL champ Hines Ward. And in fall of ’10, former “Dirty Dancing” star Jennifer Grey was hospitalized after rupturing a disc in her back — which she had broken years earlier in a car accident.
