Shauna Sand says her Frenchie ex-boyfriend doesn't have a leg to stand on -- specially the third 1 -- in his lawsuit over the release of Shauna Sand tape -- and ironically what kills him is yet another video clip in which he admits he knew exactly what he was performing when he signed up.

Shauna Sand's sexual intercourse tape partner knows a lot in the French department, but no parlez-vous Anglais ... And in the self-aggrandizement department, Berlier claims he was of "huge value" to Vivid, and not only due to the fact of "natural attributes."

Very little can quit Shauna Sand's intercourse tape from hitting the shelves now -- and it's all for the reason that Shauna has finally given the XXX flick her Lucite stamp of approval.

Hirsch states Shauna's cause for withdrawing the letter was simply because a lawsuit could show "long and highly-priced." Riiiiiiiight.
