nicole kidman billboard Happy birthday Nicole Kidman: You're 45 years old!Nicole Kidman celebrated her 45th birthday with a low-key dinner with husband Keith Urban in their native Australia before taking in Lady Gaga’s Sydney concert stop.

The couple met up with Kidman’s family for a meal at a Greek restaurant, reports the Daily Mail. Pictures of the couple leaving the restaurant show a relaxed Kidman, bundled up in a brown suede coat and scarf with her hair tied in a loose bun.

And the celebrations aren’t over: Kidman and Urban will mark their sixth wedding anniversary on June 25. Then, eldest daughter Sunday Rose turns 4 on July 7.

The Kidman-Urban family (daughter Faith is 18 months old) is currently calling Sydney home while Urban serves as a judge on the country’s version of “The Voice.”

In Kidman’s upcoming movie, Lee Daniels’ “The Paperboy,” she plays a waitress obsessed with a death row inmate:
