Mary Kay Letourneau Says Not So Fasts Vili, Moves to Dismiss His Separation Docs

Mary Kay Letourneau is nothing if not true to form ... she's now filed a bizarre petition with the court to have her husband's separation case dismissed.

TMZ has obtained a document filed just hours after we broke the story Vili Fualaau filed documents declaring the couple has separated after 12 years of marriage.

Mary Kay's documents do not cite any basis for her move to dismiss the case. We spoke with Vili's lawyer and she said he will move forward with his petition and has done nothing to suggest he wants it dismissed.

We also asked Vili's lawyer if his separation petition was a prelude for divorce, but she had no comment.

Unless we're missing something ... Mary Kay has no basis to object to Vili's decision to separate.
