In an action for libel or slander, it shall not be necessary to state in the complaint any extrinsic facts for the purpose of showing the application to the plaintiff of the defamatory matter out of which the cause of action arose. It shall be sufficient to state generally that the same was published or spoken concerning the plaintiff; and, if such allegation is controverted, the plaintiff shall establish on the trial that it was so published or spoken.
