How Josh Brolin Knew Diane Lane Would Be His Wife (VIDEO)

Both Josh Brolin's mother and his wife Diane Lane have something in common -- the willingness to be spontaneous.

"[My mother] was from Corpus Christi, Texas, a great lady ... tough lady, very independent," said Brolin on 'The Tonight Show' (weeknights, 11:35PM ET on NBC). "She would get us up in the middle of the night and she'd go, 'We're going to New Orleans.'"

Brolin then described another spontaneous trip, this time with Lane, during which he realized he wanted to marry her.
