"Lindsay Lohan's collaboration was a disaster." That's the blunt assesment given by Emanuel Ungaro, the founder of the couture house that hired the actress to advise them on a fashion line last month.

"I am furious but I can't do anything about it," fumed the designer during a meeting on Monday night at a film festival in Lisbon. Ungaro, who no longer has any contact with the fashion house that bears his name, said his creation is "in the process of losing its soul," as a result of the Lohan hiring.

The 'Mean Girls' star, 23, worked alongside designer Estrella Archs as a style consultant and debuted her first collection during Paris Fashion Week last month. The work was almost universally panned as an "embarrassment" by the international fashion press.
