Is it tacky to ask who has been invited to a party?

I think the question as asked is tacky, but as others have said, there are much better ways of getting the same information. I have friends who has a large house/yard, and I usually say something on the line of "Intimate or 500 of your closest friends?" because I rarely know more than 7-8 people at the bigger parties.

Other ways are, "Is that jerk I just broke up with going to be there?" or "Is that gorgeous cousin of yours invited?" would be so much less tacky.
