Problem with creating stub for model "Address"

Hi,

I have model name "Address".

class Address < ActiveRecord::Base
end

And I have written the stub for this model.

define Address do
  belongs_to :addressable, :polymorphic => true

  methods :id => 1,
             :full_name => 'Rob Williams',
             :street1 => 'New Street',
             :street2 => 'New Street2',
             :city => 'My City',
             :state => 'My State',
             :country => 'My Country',
             :zip_code => '123456',
             :phone => '999999999',
             :email => 'mymail@example.com'

end

But I am not able to use stub_address here. The rspec takes Address as a
plural so it searched for the Addre definition.

Is there any way to solve it?

Thanks in advance...
