Keith Urban jetted to Australia from the US to celebrate his 10th wedding anniversary with Nicole Kidman.

Speaking on stage at the Xfinity Center in Mansfield, MA, Keith said:

"We booked the tour at the beginning of the year and June 25th was going to happen in Boston. And so, I said to Nic, 'I can't work on our anniversary and so maybe we'll play Boston another time.' And she said, 'What about I come up to Boston instead?' I said, 'That's a great plan.'

"She was scheduled to shoot a film in Australia and it was going to happen last month. So everything was winding up, it was looking really good and suddenly they said, 'We're actually gonna shoot the film in June in Australia,' which threw everything out. So after the gig tonight I am flying to Australia to celebrate our anniversary."

However, Keith still got to see Nicole during the gig as he FaceTimed her and their daughters Sunday Rose, seven, and Faith Margaret, five.

Keith later took to Instagram to thank fans who had made special signs for his anniversary.

He wrote: "It was an extra special night because it was our 10-year anniversary and you guys made the sweetest signs down in the front. It was amazing, thank you so much!!!"
