TMZ Update: Haim's push to stay clean

LOS ANGELES (TMZ) - In today's TMZ Update, Dax Holt talks about actor Corey Haim's struggle with drug abuse, and his recent push to stay clean.

Corey Haim was so committed to winning the battle against his demons that he demanded a completely drug and alcohol-free environment on the set of the movie he was working on when he died.

In the days before Haim's death, Corey was working on a new film called "The Dead Sea" -- and according to one of the movie's producers, Rick Tucker, Haim made it clear that he didn't want temptation anywhere near him.

Plus, Casey Johnson -- a member of the famously-wealthy Johnson & Johnson family -- died with approximately $75,000 in assets and with no will ... according to legal documents filed by her father, Robert Johnson IV and obtained by TMZ.

In the docs, Johnson, the owner of the New York Jets, is asking the court to appoint him Special Administrator of Casey's estate. He says "it is necessary for him to take possession of all of the assets ... as quickly as possible to preserve her estate from damage, waste, injury and publicity."

The papers claim, "Members of the media have previously attempted to gain access to her personal effects." Casey's mom, Nancy Sale Frey Johnson, says in a declaration she consents to Robert being appointed Special Administrator.

And finally, Jamie Jungers is now the queen of the Tiger Woods mistresses -- which is kinda like being the thinnest kid at fat camp -- by winning Howard Stern's Mistress Beauty Pageant.

Jungers just took home the $75,000 prize after exposing a bunch of personal information about Tiger ... like the size of the club, what he wanted from her sexually speaking, and on and on. Jungers had stiff competition -- Jaimee Grubbs and Loredana Jolie -- but was able to take home the crown, because Howard felt she was "the true mistress."
