Kim Kardashian flaunted her 20.5-carat Lorraine Schwartz-designed engagement ring that cost over $2 million yesterday while going through security at LAX! Check out more photos at Bauer-Griffin. Her husband-to-be, Kris Humphries, was right behind her, and they took off for Paris, where Kim tweeted about having a short layover this morning. It seems Kim and Kris are over the moon about their plans to wed, with her recently telling People magazine, "I really fell in love with him as a person — he's such a good person with a good heart. Everyone that meets him says the same thing." There is no word yet about when or where Kim and Kris will tie the knot, but the whole Kardashian clan seems thrilled to welcome him into their large family.
