Test if a foreign key is None or not

I have a model in django that points to another model. I want to test if it's set to something or not.

model.foreignkey = ForeignKeyField(...)

I want to test if this foreignkey is set or not - without actually fetching the foreign row's data (if the foreign key is set).

if model.foreignkey: # This line fetches data for 
    <dosomething>

Any help?
