It makes sense. His home is in Nashville. He can't stay in Australia forever.
I live in Nashville and used to unintentionally run into him and Nicole all the time here.... at the park, having breakfast at a local restaurant, having coffee at Starbucks. They're a nice couple who try to live normally in this city and usually they can blend in.
So it doesn't seem like I'm bluffing, I took this pic last year (Oct. 2011). I apologize for it being very unflattering.
