SHE raised eyebrows when she kissed Big Little Lies co-star Alexander Skarsgard on the lips in front of husband, Keith Urban at the Emmy Awards. But Nicole Kidman says she simply has a "different connection" with the actor after they shared some "intense" scenes in the hit series.

Talking to W magazine, in which she appears on the cover with fellow Aussie Margot Robbie, Kidman says she and Skarsgard put all of themselves into playing Celeste Wright and violent husband, Perry, and came out of the experience bonded.

It was when Skarsgard won his Emmy Award that Kidman planted the kiss on his lips.

"To be able to just give him a kiss, I mean, I'd kissed him many, many times on the set. Much more than that," she said. "So that was just my way of going, in the moment - we were both shocked and we were like, 'Oh, my gosh, I'm so glad you won.' Because I know what he put into that role."

"There were times on that set when it was intense. But he and I communicated," she said. "There had to be such safety and such honesty and such raw vulnerability there that we have a different connection."

"He [Skarsgard] never pulled back and he never talked about, never worried about, how he was being depicted. He was just very honest and very true to what the story needed," she said.

Her real-life husband Keith Urban however found the whole series "disturbing".

"When he watched Big Little Lies he was disturbed", she explained. "He says that when he hears me scream or cry from a certain place in my soul it's almost like it goes straight into him and he has a visceral reaction immediately.

"Because his brain and his heart doesn't discern between acting and real life. They're the same sounds for him. It throws him," she said.

Both Kidman and Skarsgard are up for Golden Globe Awards this weekend for their Big Little Lies roles after the show walked away with a bag of Emmy Awards.

Kidman also opened up on her first date with Urban and how she fell for him quickly.

"I remember my first date with Keith. Mm-hmm. Picked me up on a motorbike, took me to Woodstock. My kind of guy. Hey, we're married! It was a good date," she said.

Kidman, who met Urban in January 2005 and married him in June 2006, says she wasn't always so lucky in love growing up.

"I was, like, a really tall, skinny, freckly red-headed girl," she said. "I can't remember my first date. I was, like, not that popular, I have to say."
