CONRAD MURRAY'S MOM She Doesn't Know Jack (Daniels) About Her Son

Note to Conrad Murray's mom.  You were wrong when you told Judge Michael Pastor your son never had a drink in his life, and we have the proof -- 80 proof.

Murray's mom wrote a letter to Judge Michael Pastor before his sentencing, pleading for mercy for her son and claiming Conrad is a good person who "never drank alcohol, took drugs or smoked cigarettes in his life."

But here's the deal.

 We got this pic of the Doc, who was at a holiday bash in Vegas in the late '90's.   You see
Murray triple fisting.  People at the party tell us Murray was drinking champagne and cocktails all night long.

At least he won't get extra jail time for this lie.

MICHAEL JACKSON'S KIDS Watching a Movie, Not the Trial

With the fate of Conrad Murray still hanging in the balance, Michael Jackson's children -- Prince, Blanket and Paris (in the white hat) -- went to the movies last night and saw "Tower Heist."According to our sources, Katherine has been filling the children in on the details of the trial herself -- she'd rather they hear it from her and not through anyone else.

We're told when the verdict comes down, Katherine will be the one to tell them the news. 

Jurors did not reach a verdict on Friday and deliberations will continue Monday morning.
