hey mama...

I wonder if Ollie know who Julie Chen is? Last night on the live show - he greeted Julie with "Hey Mama." I think he has no idea that she is married to the head of CBS. I mean is he trying to be cool?
I don't think this is the first time he has addressed her in an off-color manner. It seems like he did the same thing on another eviction show. I mean Julie corrected Dan when he called her Mrs. Chen. Maybe someone will let Ollie know - that Julie Chen is not his mama?
