What is the best way to use a model from a helper?

Okay cool, makes sense. Thanks! If I've already loaded the model in the controller that is rendering a view that is calling functions in the helper, do I need to re-load the model in each helper function?

I'm guessing that to do so won't hurt anything because CI won't load a model it already has loaded. Correct?
