Keith Urban and Nicole Kidman have been in a celebratory mood lately.

Last week, the couple shared a romantic dinner at the Nashville restaurant Flyte where they celebrated their fourth wedding anniversary. Over dinner the lovebirds got cozy in an intimate corner of the restaurant – which is a Nashville favorite frequented by stars such as Shania Twain, Gwyneth Paltrow and Taylor Swift.

"[Nicole] looked stunning, very understated in a sleeveless dress and sandals," says one observer. "They were smiling and holding hands across the table. You could tell they were so in love."

After their meal, the twosome chatted with restaurant staff, who described the couple as "a delight."

And that wasn't the only night for partying: On June 20, they had a joint celebration for Kidman's 43rd birthday and Father's Day. Another birthday cake is in store for the family when Sunday Rose turns 2 on July 7.
