Hotel heiress Paris Hilton has reportedly lost her advertising contract with German directory website GoYellow because she parties too much. According to the online edition of German tabloid Bild, the three-year contract was prematurely cancelled because Hilton's wild lifestyle conflicted with the values of the communications business.

The company argues Hilton's notoriety was no longer good press for the venture. GoYellow boss Dr. Klaus Harisch tells the publication, "Paris helped us a lot last year to make our product known. But within the last months she hasn't moved on from being a party girl to become a businesswoman, as it was agreed. At the moment, she isn't a co-operation partner who identifies sufficiently with our product."

GoYellow and Hilton signed the contract last year.
