Anna Nicole's Sis -- Pay Me for Selling Out Anna!

Anna Nicole Smith's half-sister is suing the publisher of her book, "Train Wreck: The Life and Death of Anna Nicole Smith," because she claims she hasn't been paid for exploiting Anna Nicole's tragic death.

According to a lawsuit filed in Los Angeles Superior Court earlier this month, Donna Hogan claims she never actually entered into a final written contract with Phoenix Books and Audio, Inc. She claims they went and published it anyway, but more importantly, they did not:

-- Promote it
-- List her as the sole author
-- Pay her 40% of the gross receipts
-- Try and sell the book to Europe
-- Attempt to sell the movie rights
-- Pay her $200k upfront

She is seeking unspecified damages.
