Michaele Salahi Injected Into Plastic Surgery Lawsuit

TMZ.com:

Suspected White House Crasher Michaele Salahi may need to save more face than Botox can handle -- because the "Housewives" star is being sued for allegedly stiffing her plastic surgeon. 

The man behind the lawsuit is Dr. Navin Singh -- from Ivy Plastic Surgery in Maryland -- who tells TMZ, he performed several "procedures" on Salahi last April -- but Michaele never paid the bill in full.

According to the suit, filed in federal court in Virginia, Salahi still owes a cool $500 for unnamed procedures.

Dr. Singh wouldn't confirm the nature of the procedures -- but according to sources connected to the lawsuit, it's all over unpaid Botox injections ... which we're told Salahi had requested for a fundraising event a few days later.

A rep for Salahi -- who has been ordered to face the charges in a Virginia court on September 17 -- tells us, the DC housewife did in fact see the good doc in question ... but as far as she's concerned, the bill was settled.

With all the people claiming that the Salahi's owe them money, it'd be pretty stupid to business with them at this point.
