FlattFan, I'm not suggesting she can sue. I was only saying that IF it were a real ad by a real company using her name improperly, THEN she would have grounds to sue. I was arguing that no company would be so stupid as to lay themselves open to such a lawsuit, therefore the video could only be a joke. At least that's what I was trying to say.
I don't think she has any grounds to sue over being the butt of a joke. Well, I don't know anything about Italian laws and practices. But in the USA, pretty much any celebrity is going to be the butt of jokes from time to time and I've never heard of them suing anybody for making fun of them. For example, the movie Team America: World Police (by the makers of South Park) made ferocious fun of Alec Baldwin, Danny Glover, Susan Sarandon, et al. South Park itself is constantly mocking celebrities by name. I don't think the producers get in any legal trouble as a result. (Surprisingly enough!)
