Diana star Naomi Watts has shared the story about when she and now husband Liev Schreiber first met, revealing that he almost got away -- and she wasn't about to let that happen.

"It was a lot more ballsy than I would ever normally be," she says in the November issue of Allure magazine.

"Normally I want a guy to make the first move, and he wasn't. Then he got up to say he was leaving and I was like, 'Oh, s***. Probably another couple years are going to pass by. I was wildly attracted to him and his work, so I said something cheeky as he was about to walk out. I said, 'Don't you want my digits? Because I couldn't possibly say, 'Would you like my phone number?'" she explains. "It made him laugh. He texted me five minutes later saying, 'Would you like to go for a drink now?' And I said, 'No, I'll meet you for breakfast tomorrow.'"

Watts also discussed her recent role as the late Princess Diana.

"I thought, Everyone's going to jump to these comparisons: She's not tall enough. She hasn't got the nose. She hasn't got the voice. I thought, 'It's not going to work, it's too scary. So I said no," she explains. "But for some reason, I didn't feel completely at peace with that decision. It was nerve-wrecking every step of the way until I was there, and then it was like, 'Okay, now I'm just doing it."

"Diana" opens in the U.S. on November 3.
