On wedding crashers thing, seems like the mother is that Kennedy who didn't approve her. Remember the story from tabloids about members from that family who questioned her motives? And it seems like it's just a miscommunication, Conor being the stubborn boy, ignored the bride mother's reply and insisted to bring Taylor. I don't know, I just don't buy the mother's story. There was definitely something happened, but thinking that she (maybe) already disliked her, not possible to put some twists on the story.
Also, I'm still waiting for the apology letter from the media on accusing her as a crazy stalker/clinger.
