The `J. Edgar` star - who has previously dated Rachel McAdams, Salma Hayek, and Anne Hathaway - admitted it was a life threatening confrontation with a mountain lion in Big Sur, California, that convinced him his girlfriend, who he refused to name, is the woman for him.

Speaking on 05.01.12 `Tonight Show With Jay Leno`, he said: "I knew (she was the one) on a kind of interesting trip that we took. I was doing this great movie in Big Sur, California and it was a very, very low budget movie. Often times they put you up in these terrible, little hotels and so they said you have $30 a day of a hotel allowance. And I used that money to find my own place to stay. And there`s this guy who has an eco resort. We stayed there and had our first night. It was absolutely wonderful.

"The next day she stayed in the trailer, I hiked down and went to work. And we worked that day at this beautiful house in Big Sur and all over this house were signs that said, `Beware of mountain lions.` What to do in case you see a mountain lion - all the noises you`re supposed to make, clanging, yelling, make yourself as big as possible.

"That night, I then go home at 4 o`clock in the morning and I don`t have a flashlight. And as I`m going up, I get to the point where I can see nothing, I am now going along hand by hand and I hear, totally serious, two big breaths, and six feet above me, I see the very slight glint of the eyes of a huge mountain (lion) and I literally proceed to do what I had just read in the instructions. And I started screaming and yelling and literally being as crazy as I could be. It padded off and just slowly went away and I worked my way into the trailer and I got in and I decided at that moment that this woman was the woman for me."
