Following a rough week in which she fainted during rehearsals, reality TV star Lisa Vanderpump was the latest star to be voted off the ballroom floor of ABC's "Dancing With the Stars."

"It's been six long weeks I have to say, and boy, it's taken a toll," Vanderpump told ABC News backstage after her elimination. "It's the hardest thing I've ever done."

Vanderpump, who stars in "The Real Housewives of Beverly Hills," had struggled throughout the competition. Her busy schedule combined with the grueling physical requirements of rehearsal led to her collapse during practice this past weekend, and judges acknowledged that her performance of the cha cha cha on Monday had suffered due to the lack of rehearsal.

"It was just a perfect storm. It was just swollen glands, a fever, my blood pressure was low, everything," Vanderpump explained.

Vanderpump, 51, smiled when the results were announced on the show Tuesday night, and thanked her pro dance partner, Gleb Savchenko, saying being paired with him was "a gift."

"Thank you for giving me a last dance," Savchenko told her. "It was really good."

Vanderpump's daughter also praised her mother's accomplishments on the show.

"She is incredible. Amazing," Pandora Sabo said. "It is so inspirational to watch. She is my hero."

Vanderpump and boxer Victor Ortiz had been the two lowest scorers following their performances on Monday night - where she tied with Ortiz for last place. The star with the lowest overall total after judges' scores and viewer votes are combined is the one who is voted off the show. Country music legend Wynonna Judd was eliminated from the competition last week.
