Mercedes Javid paid homage to Denise Richards' character in 'Wild Things' by squeezing into a micro thong swimsuit for a very soapy and public car wash/cry-for-attention.
M.J. shamelessly posed while putting a shine on her Volkswagen SUV in L.A. -- even though the city's in the midst of severe drought.
She's been very open about her dramatic weight loss over the last year, which she chalks up to a healthy appetite for sex.
Still ... washing a car is a pain in the ass.

Nicki Minaj's "Anaconda" music video is filled with ass -- but now, thanks to the glorious power of the Internet (and some editing software) ... it's also got a lot of gas.
A comedy duo out of South Africa named Derick Watts and the Sunday Blues released the flatulent remix late Tuesday night.
The concept might be is definitely juvenile ... but we dare you to watch it without cracking a smile.
For those who haven't seen Nicki's original -- SHAME ON YOU!!
