Lydia was the third wife of Gary Heffley. It is unknown why they divorced. When they got married, her head was taped over the head of Charlene on the picture of Gary's second wedding, by Susan. In Gary's fourth wedding Sonja told him to get rid of her name as a tattoo on his arm, but he couldn't pay enough money, so he instead changed it to "I am not in love with Lydia anymore". Lydia was in cursive and had a heart instead of a dot. The rest was a simple black font.
