Lindsay Lohan is blasting reports that she's agreed to strip down to her birthday suit for a full-frontal photo spread in a "sex book" ... calling the whole idea "gross."
TMZ has learned ... Lohan is telling friends she would "never do a sex book" ... despite reports that she signed a multi-million dollar deal to pose with James Franco in a series of "graphic" photos for a Madonna-esque book with photographer Terry Richardson.
However, we've learned Lohan HAS agreed to a milder photo shoot with Richardson ... in a book about the "glamor and history" of Hollywood.
No word if Franco is involved in that shoot ... but it's probably a better career move than hosting the Oscars.
Lol dis bitch.
IT'S NOT LIKE WE ALREADY HAVEN'T SEEN YOUR INFECTED BEEF CURTAINS!
