The New York Post are holding Michael Douglas's ex-wife responsible for their son's actions:

"Maybe the judge should have tossed druggie Cameron Douglas' jet-setting mom in the slammer, too - for poor parenting. Glamorous globetrotter Diandra Douglas - the ex-wife of Academy Award winner Michael Douglas - chose to vacation in Mallorca, Spain, rather than stay with their drug-peddling son after a judge put Cameron under house arrest at her Upper East Side town house, friends and family told The Post. 'It's moves like this that make you just want to shake Diandra. She just didn't pack up and fly home,' a longtime friend of the Douglas family told The Post. A pal of Cameron added, 'She left [him] with no parental supervision... Most of us thought the right thing to do would have been to tell the judge, 'Keep him in jail until I get back,' " the friend said. Records show Cameron was under the watch of paid guards at Diandra's $9.2 million mansion on East 65th Street when - fewer than two weeks after his arrest - his girlfriend, Kelly Sott, tried to smuggle heroin into the house in an electric toothbrush. Both were arrested. Last week, Cameron was sentenced to five years in prison for peddling crystal meth. 'In Diandra's defence, if she'd been home, she never would have let Kelly in the house,' one family friend said. 'But the fact is, she never came home'."

Let's back track to the mate saying "She left him with no parental supervision." Um, in the event that "parental supervision" is still required for someone who's 31 years of age, what of the whereabouts of his other parent?

In yet more uplifting news, 54-year-old twice divorced Diandra is also "mother to twin 6-year-old boys, born to a surrogate, and a 5-year-old daughter adopted from Kazakhstan."

Dog. Licence required. Etc.
