Tom Hanks: She Screwed You ... Yeah Yeah Yeah!!

Rita eventually dropped the lawsuit after resolving a misunderstanding about the conditions of the sale.

Pearl provided authentication of the Beatles poster, which she herself had purchased from Sotheby's London.

Tom Hanks is being dragged into the middle of a legal war over The Beatles.

Tom's wife, Rita Wilson, just had to have a 1962 vintage Beatles poster priced at $75,000 as a gift for Hanks.

According to legal papers filed in L.A. County Superior Court, Wilson agreed to ante up -- provided the seller, Melissa Pearl, coughed up a certificate of authenticity. When Pearl came up dry, Wilson said she would bail on the deal.

That's when Pearl, "became belligerent" demanding not only the $75k but an additional $300,000 "for what Pearl absurdly characterized as her time and trouble to obtain the evidence requested by Wilson that the poster was authentic."
