What do you get for the actress who has everything?

Country star Keith Urban gave wife Nicole Kidman quite the surprise party on Saturday night, the day after she turned 41, People reported.

Urban sang “Who Wouldn’t Wanna Be Me” to his pregnant spouse at Chicago’s Soldier Field, then asked the sizable audience to serenade her with a birthday classic.

“It would be nice to have 50,000 people sing ‘Happy Birthday’ to her,” he said as Kidman took the stage, and the crowd obliged.

Following the serenade, Kidman blew the audience a kiss and returned backstage.

Kidman is due any day now with the couple’s first child and has another baby on the way: Baz Lurhman’s period epic “Australia,” her second film with the outlandish director following 2001’s “Moulin Rouge.”
