I didn't watch the Leno show. Probably won't --- I'm just nowhere near a TV most nights at 9 Central. But, I like Leno as a host and all.
Kanye: So, he says he was wrong. Great. What about his Tweets (that's what they're called, right?

, or is it "his Twitterings"?) after the VMA keeping on about Beyonce's video being the best, in all caps, etc. Did he say he was wrong about keeping on with it after it was over?
No, he waited until the public blowback was overwhelming, and he took an opportunity to make a splash on the new hot Leno show and blah, blah, blah, and "owned up" to being wrong.
The proof is in the doing, and for his sake, you can hope he "improves". All this celebrity apology stuff is old road --- run over, rutted, repaved, run over, rutted, repeat. Maybe he can join a "bad sport rehab camp" with Serena Williams and Roger Federer.
What I figure'll happen next is that some publicists, agents, and record producers will drum up a way for him and Taylor Swift to record a duet. That'd be par for the course, wouldn't it? The song could be called, "I'm A Little Fake Country, and I'm A Little Bit Smoke What I Roll."
