is Kareena a fake?

I am suspecting she is putting a fake act for sure. In jami raja always they start as good ones only to turn bad. But this pagal natak is really disgusting to me. Plus all that overacting. 

Exactly i also think kareena is just acting and she will be bad like her mother shabby and will be behind karan..and true it is shock that bunty became bad that he left krtika ..anything happens in serial world
