well it hasn;t been officially confirmed yet about reese witherspoon's third pregnancy. but i think it's pretty obvious here with this photo that was just released that she is indeed pregnant! aww congrats to her and jim toth and her growing family! this picture here was taken at a beach in Costa Rica this week. so it's pretty recent. she is wearing a one piece black bathing suit here, the appropriate suit when being pregnant!
