Powerhouse attorney Lisa Bloom sent Ferrari a letter -- obtained by TMZ -- warning him not to sell or post any nude pics or images he might have of her. Bloom says, "Posting online or distributing photos of Ms. White's intimate body parts is a crime punishable by fines and jail time."
And for good measure ... she also brought up California's revenge porn law. Remember, Ferrari already came within a nipple or so of semi-nudes ... when he posted pics of himself and Chyna in bed.
Ferrari -- who already bounced out of BC's picture and returned a bunch of jewelry he bought for her -- is officially on notice.
