Carlton, best known for singles like "A Thousand Miles" and "White Houses," has been previously linked to John Mayer and Third Eye Blind frontman Stephen Jenkins. This is the first marriage for Carlton, who announced in October that she and McCauley were expecting a child. However, she revealed a month later that she had experienced an ectopic pregnancy and had to have her entire right fallopian tube removed.
