I have seen these types of people pop up in Silicon Valley over the years. Often, it is the sibling of a movie star, but it's the same idea. They typically do not know anything about technology and also are amusingly out of touch with the culture of the tech industry. They get hired because they are related to a famous person. They do not contribute much. I think they should just stay in LA.
EDIT: I just want to add that I don't know anything about this woman in particular (I'd never heard of her before yesterday), and it's entirely possible that she is the lone exception to the generalization I'm describing above. All I can say is that when I have seen these Hollywood people turn up in SF tech circles in the past (which has been several times, actually), it's always been the same story.
