Tareq to Michaele: You Screw Me, I Screw You

Banging a rock star can be a really expensive proposition ... so Michaele Salahi is about to find out.

TMZ has obtained a copy of the prenup between Michaele and Tareq. Under the terms, if Michaele commits adultery, she automatically loses her right to any money or other property they accumulated during their 8-year marriage.

Under the prenup, by moving out, she's also forfeited her right to spousal support.
