Michael Salahi Deals Blow to MS Charity

First the dog, now people suffering from Multiple Sclerosis .... more collateral damage caused by Michaele Salahi's decision to bang a Journey band member.

Tareq Salahi tells us he's forced to cancel an MS charity event Saturday because he's left without a performer now that Michaele has abandoned him.

Tareq and his Groupie Slut were throwing the shindig at their Virginia Winery. The highlight of the evening -- dare we say, "the draw" -- was Michaele singing her mind-numbing not-a-hit club song "Bump It."

So now the event is on hold, until Tareq can reschedule with a new act.
