A method is provided for reducing the density of a well cement composition for cementing in a subterranean formation. The method comprises providing a cement composition that comprises water and a cement, and then adding an additive comprising an anionic foam stabilizer and an anionic foaming agent or a Zwitterionic foam booster. A gas is added to this mixture to reduce the density. Further, foamed cement compositions and additives for foaming and stabilizing a well cement composition are provided.
