Hollywood star Nicole Kidman has paid a touching tribute to her father Dr Anthony Kidman, describing the late psychologist as her 'confidant and my protector'.

The Others actress wept as she laid her father to rest at his funeral held in St Francis Xavier Church in Lavender Bay in Sydney.

Dr Kidman, a respected clinical psychologist, suffered a heart attack in Singapore while visiting his younger daughter Antonia. He was taken to Tan Tock Seng Hospital where he was later pronounced dead.

Joined by her husband Keith Urban and their children Sunday, six, and Faith, three, Kidman recalled him always being there for her, especially in the wake of her split with Tom Cruise.

"He was the father that was on a plane, hours after I got divorced, to come and take care of me, staying with me for weeks for as long as I needed," she told mourners.

"He was also the father who would when I was crying always tell me 'Nicki, it's going to be OK'."

She continued: "He was the father that would come to the principal's office after I forged his signature because I was wagging.

"The principle would ask 'Is this your signature?' and he would say 'yes!'," Kidman said to laughter from the congregation. "I'm a girl, a woman that was raised by an extraordinary man, a good man, a compassionate man, a strong man," she said.

Kidman and Urban serenaded the congregation, which included younger sister Antonia, husband Craig Marran and their six children as well as Russell Crowe and his ex-wife Danielle Spencer, with an acoustic rendition of Amazing Grace.
