The Moulin Rouge! actress and New Zealand-born Urban reportedly got engaged over the US Thanksgiving weekend (24-27NOV05) in Nashville, Tennessee, where they celebrated the holiday with both their parents.
He says, "I've spoken to Nicole a couple of times recently and it was clear she's enjoying great happiness right now.
"Hanging out with Keith is giving her a lot of joy and I'm happy for her."
He adds, "A relationship under that microscope doesn't get the chance to evolve.
"It happened to me some years back. My summer was ruined as we were never left alone."
