'Shahs of Sunset' Star Mercedes Javid -- 'F*** the Drought!'

"Shahs of Sunset" star Mercedes Javid sees nothing wrong with shamelessly washing her car for a photo op ... declaring, "F*** the drought!"

Javid was out Tuesday night at Bootsy Bellows in West Hollywood and she's clearly wasted. When our photog asked about the car wash pics, her reasoning was compelling, we say sarcastically.

Be sure to watch til the very end if you want to see more of MJ than perhaps should be allowed.
