MIAMI Vice star Don Johnson used to know how to party – sex, drugs, rock and roll, a lot of women and two marriages to Melanie Griffith.

Despite his wealth and success, he was a mess.

Then he woke up, calmed down and married a Montessori teacher and life’s been fantastic ever since.

Strange, isn’t it, how for so many men, the best wife is one used to dealing with infants?
