Being super drunk in public alone tops being drunk in public and getting drunk-married in Vegas, losing custody of your children, and being hospitalized on the train-wreck scale? Leave Christina alone!

But yeah, that's not so bad. My parents have both been publicly drunk at one time or another and they aren't irresponsible people. Divorce happens. Sometimes people are just naturally a little underweight for their height. I personally have both forgotten the lyrics to the National Anthem (luckily I could just move my mouth while the rest of the choir sang) and stumbled on the same night even, and I've never so much as smoked a cigarette. It seems to me like she still has it together for the most part.
