Kanye West went all Dr. Jekyll and Mr. Hyde when the topic of his war with Wiz Khalifa came up just now at LAX.

Kanye was clearly NOT in the mood to talk about the beef, but you have to see his reaction to our guy asking if he regrets bringing Wiz’s kid into the conversation.

Just watch … it’s extraordinary, because Yeezy briefly flashes back to the guy who was always angry at paparazzi — and then, just as quickly, he bottles that anger.

The way this clip ends is remarkably friendly.
