Nicole Kidman waited four months for Keith Urban to call her.

The 49-year-old actress was instantly smitten with the country singer when they met for the first time in January 2005 but she insists the feeling wasn't mutual.

She said: "I had such a crush on him and he wasn't interested in me. It's true! He didn't call me for four months."

And Nicole has never asked Keith - who she went on to marry in June 2006 - why he took so long to get in touch.

She told talk show host Ellen DeGeneres: "There's certain things -- and I think anyone in a marriage would agree with this -- you just leave there. We're here now and it's all good we don't need to hash up all that stuff."

This weekend will see the 'Lion' star in London for the BAFTA Awards while her 49-year-old spouse is in Los Angeles for the Grammys.

And after realising they wouldn't be able to support one another, the couple's eight-year-old daughter Sunday offered to be her dad's date, a proposal which Nicole - who also has six-year-old Faith with Keith and Isabella, 24, and Connor, 22, with ex-husband Tom Cruise - quickly shut down.

She explained: "Because she's eight and they use inappropriate language."

Nicole is also nominated for Best Supporting Actress at the upcoming Academy Awards and admitted she can barely remember her first Oscar win, for 2002 movie 'The Hours'.

She said: "I sort of have snippets of memory of it. And I've actually never rewatched my speech, can you believe that?

"But it is sort of like a dream when you win something like that cause there's so many people watching. I didn't expect it because I hadn't won certain other awards, so I was sort of blindsided by it, but at the same time just beyond thrilled."

But this year she is "so badly" to scoop the honour as she never thanked her late father in her first acceptance speech.

She said: "I was so focused on thanking my mom because I wanted to thank her and she was the one sitting right there, and there's something about that mother-daughter relationship.

"And my dad was the kind of that, he's not alive anymore, but the most beautiful man where none of that was important to him. He was always sort of like, 'Oh don't worry about me, thank your mother!' "
