The 49-year-old actress met the actor - who she was later married to for 11 years - on the set of 'Days of Thunder' in 1990 and admits she was in awe when they first came face to face.

Speaking in The Jess Cagle Interview, she said: "I remember walking in, I remember being so nervous and seeing Tom Cruise drive up in a Porsche, I think it was. He got out of the car and walked through and I was like, 'Ah.' My jaw dropped.

"Then I had to go in and audition in front of Tony Scott. Sweet Tony. [Producers] Don Simpson, Jerry Bruckheimer, Robert Towne and Tom. I was like, 'No way, I'm not going to get this.' They called that afternoon and I had the job.

"I was just like, 'Oh my god, Mom!' Yeah, that was huge. Huge. You know, obviously, changed my life extraordinarily. So grateful for the film, for everything that came with it. It was a big, important part of my life."

Meanwhile, Nicole - who adopted Isabella, 23, and Connor, 21, with Tom and has Faith, five, and Sunday, eight, with her husband Keith Urban - previously opened up about Connor and Isabella's "need" to know who their biological parents are.

She shared: "Every family's experience with this is distinct and private. But we live in an ever more transparent world, technologically speaking. Kids are resourceful and the need to know your origin story is universal."

And Nicole recently confessed she would have loved to have more kids with Keith.

She added: "I wish I could have met him much earlier and had way more children with him. But I didn't. I mean, if I could have had two more children with him, that would have been just glorious. But as Keith says, 'The wanting mind, Nicole. Shut it down.'"
