Lisa Vanderpump Faints During 'Dancing with the Stars' Week 4 Rehearsal

Zap2It.com:

Everyone who competes on "Dancing with the Stars" talks about how rough the training can be. That only gets worse if a celebrity is sick. Lisa Vanderpump may have found this out in "DWTS" week 4 -- the "Real Housewives of Beverly Hills" star actually fainted during rehearsals.

Although "DWTS" and host Tom Bergeron didn't give much away at the beginning of the show, it was immediately apparent that Lisa wasn't good to go. She didn't come out onto the stage with her professional partner, Gleb Savchenko, and had also missed her dress rehearsal.

Tom said that it was only up in the air about whether Lisa would perform, but rehearsal footage indicated that dancing was unlikely. Right in the middle of a dance move, the cameras caught Vanderpump collapsing in what looked like a faint.

"By the time Thursday rehearsals rolled around -- let's just say I was exhausted and everything felt off. Gleb and I were rehearsing our cha cha and suddenly I just blacked out," Vanderpump wrote in a blog on People.com. "The doctor found that I had a viral infection with fever and swollen glands. And between trying to fight that and all of the stress on my body from running around, I ended up with low blood pressure and a rapid heart rate, which is why I fainted."

As for the performance show this week, all Lisa would promise is: "I will give it my best!"

It wasn't decided until about 15 minutes before the show ended, but Lisa Vanderpump did indeed dance for the "DWTS" performance show. Her cha-cha was rocky and the star didn't look terribly good, but she did get through it. The judges awarded Lisa and Gleb 18 points.
