London, Nov 21 : Tom Hanks'' wife Rita Wilson is caught up in a legal battle over the non-payment of a ‘The Beatles’ poster.

The actress made a deal to pay 50,000 pounds for a vintage picture of the Fab Four to seller Melissa Pearl.

Wilson was buying the poster for her actor hubby.

However, the only condition she had was that Pearl had to provide proof of authenticity, according to papers filed at Los Angeles County Superior Court.

But when Pearl failed to furnish the proof, Wilson backed out of the deal, according to celebrity website TMZ. com.
