The most beloved Beverly Hills housewife, and more recently a front runner on the 16^th season of Dancing With The Stars (DWTS), Lisa Vanderpump, fainted while rehearsing the Cha Cha for the celebrity dance off.  Lisa Vanderpump, who is also a restaurateur, designer, author, and philanthropist, posted in her blog today that the constant rehearsals, flights around the country, and business responsibilities put such a strain on her tiny frame that her body gave up on her.

Lisa Vanderpump's faint occurred on Thursday while she and her new-to-the-show dance partner, Gleb Savchenko, were perfecting their steps for the upcoming episode of Dancing With The Stars.  Lisa blogs that Savchenko excels at the Cha Cha over all of the other dances they perform, so she didn't want to let him down and pushed herself too hard. 

The 53-year-old housewife and mother of two went to the doctor and was informed of low blood pressure and a rapid heart rate.

The multi-tasker's opening slogan on Real Housewivees Of Beverly Hills is "Life isn't just diamonds and rose', but it should be." Lisa is no stranger to the booze and often seen with a pink drink in her hand.  It is definitely time for her to slow down and take a breather, although she blogs that she WILL be performing the Cha Cha with Gleb and she expects to be the next DWTS champion.  

Blacking out is very dangerous and your body's way of telling you to slow down.  Celebrities such as Lindsey Lohan, Justin Beiber, Kelly Osbourne, and Lady Gaga have all felt their inner lights go out.  It seems showbiz can be overly stressful, and the Brit is too entertaining on Housewives to leave us so soon.

None of Lisa Vanderpump's co-stars from Real Housewives of Beverly Hills have yet commented.
