Michael Douglas's son Cameron has been given one more chance to get clean today by a judge who sentenced him to five years in prison — just half of the supposed 10-year minimum — for possessing heroin and conspiring to sell crystal meth. After Cameron, 31, pled guilty earlier this year, his father Michael, grandfather Kirk, stepmother Catherine Zeta-Jones and even Miami Heat coach Pat Riley wrote letters of support. "My stepson is a caring, considerate, worthy human being; but nevertheless, the disease that for years he has tried to combat, did take over again," Catherine wrote. "What is wrong, is wrong, but may all these positive attributes prevail so that a facility that he is positioned in will help rehabilitate him." Cameron had told the judge that he was sober for the first time in his adult life.
