— -- Nicole Kidman and Keith Urban celebrated their ninth wedding anniversary surrounded by fans.

The singer shared a video featuring his actress wife to thank the people who came to his Michigan concert last night bearing congratulatory signs for the couple.

"You have no idea how touching that is," Urban said. "Literally, I was trying to hold back tears, it was so beautiful." They were everywhere, so we were just so grateful."

Kidman, 48, gushed that the showing was "amazing," while Urban, 47, called it "magical, celestial and so romantic."

"It was so fun," he added. "We should come back here every anniversary and play."

The couple, who are now parents to two girls, said "I do" in Australia in 2006. They've since made a home in Nashville.
