The "Dancing with the Stars" celeb was taken to the hospital.

JANE SEYMOUR's representatives have confirmed that the actress and "Dancing with the Stars" contestant was taken to the hospital on Tuesday. As the show opened that night, Jane's partner TONY DOVOLANI appeared alone.

"Dancing with the Stars" host TOM BERGERON announced that Jane's absence was a result of food poisoning.

Then, when the first round of couples found out they would dance another week -- Jane and Tony among them, Tony said, "She is going to feel a whole lot better when she finds out she is safe."

Earlier in the evening, Jane was dressed and ready to take the stage, but her competitor HELIO CASTRONEVES told ET that she became nauseated and got sick while waiting for the show to begin. Helio also mentioned that Jane was placed on a stretcher, and fellow competitor JENNIE GARTH told us that she saw Jane being taken away in an ambulance.
