Lilly was once married to Canadian hockey player Murray Hone, and is believed to have ended her relationship with her former Lost co-star Dominic Monaghan. Her known nicknames include “Evie” and “Monkey”. Her Lost castmates nicknamed her “Monkey” because of her ability to climb trees with ease, a skill which has been incorporated into her character. Her fellow Lost-actor Josh Holloway also calls her ‘Freckles’, sharing the nickname his on-screen character Sawyer gave her. She is also known on set for her tomboyishness, Christian faith, and her “potty mouth.”
