According to Us Weekly Nicole Kidman and Keith Urban announced today that they returned to Australia today to prepare for their upcoming wedding.
So it looks like it will actually happen, despite all of the rumors about problems in the relationship. Personally, I don't have much interest in them, but for the fact that I chose them for my fantasy league team this week (rosters had to be set before the news broke). I think this should get them a good amount of press coverage. So I'm actually quite excited.
