<human>: "Arizona had a breakdown September 2011… I was away from NYC, but she called me desperately, pleading for help. At that time, Nikko had three nannies because she was working so often and trotting him along from country to country with her. She begged me to rush to NY so I could care for my son full time, I was more than happy… I dropped everything and moved immediately.

She had/has a major problem with alcohol, painkillers and amphetamines. I was shocked, had no idea…. but of course I did everything I could to help her… including pretending we were the perfect family. 

She skipped two seasons walking the runway because she was "incapable of being videotaped", she was literally so out of it most of the time, she wasn't showing up to work. Her agency NEXT must have been so pissed. We decided to move to London June 2012, to hopefully help change her patterns.

Everything just kept just getting worse and worse. She has three doctors; in different countries prescribing her "amphetamine salt" and painkillers to help her stay thin, awake during long days of shooting, and still be able to sleep at night.

Early this year we had a falling out, she was so paranoid, projecting all of her issues/insecurities on me… I basically told her I wanted full custody of Nikko and I filed a residence order with the courts in London."
