Kim Kardashian recently got engaged to her beau, basketball player Kris Humphries, and she took time off from wedding planning to visit 'The Tonight Show.'

Host Jay Leno was interested to find out how long it took for Kim to know that Kris was "the one," and seemed taken aback when she said she hadn't known immediately. But, it only took until "month two" of the whirlwind romance for her to be sure.

Then Kim spilled the beans of the exact details of Kris's oh-so-perfect, ultra-romantic proposal. (Guys might like to take notes here, as many prospective Bridezillas are sure to be wanting their boyfriends to "do a Humphries" for their own marriage proposals.)
