You gonna work something in about her half-sister? I don't see why this is news; it annoys me when yet another media outlet reports on it.
The worst of it is that she didn't say it at first, yet...she did. "I have a REALLY BIG SURPRISE GUEST next week! I've NEVER been so surprised!" she said. If it wasn't a lost sister, what else could it be? How dumb did you have to be to not figure it out then?
