This Sim had a major role in some of Lifesimmer's let's plays.
She and her faternal twin brother Kayden spent the majority of their childhood travelling due to military parents. They wanted to settle down in the place they always had dreamed of - Isla Paradiso. When they were finally old enough to be responsible for their own, they moved out into a houseboat.
At the beginning of the LP Kylie purchased a resort, naming it Kylie's Retreat. The LP finished with Kylie as an elder - she never married or had kids, unlike her brother, who had a mermaid wife and two sons by the end of the LP. She did however frequently flirt with Carmen Farris. Lifesimmer originally planned for her to adopt a baby girl, however that never happened. Instead she adopted Milo, a kitten which she treated like her baby.
- Lifesimmers description of pre-series indicates that Kylie lived in Lunar Lakes, Hidden Springs, France and Setra before she moved to Isla Paradiso with Kayden.
- Identity of her parents is unknown. However, Lifesimmer said that they were both military generals and they traveled all around the world.
- In episode 31 of Island Paradise LP, Lifesimmer kicked her out of household, but she moved her back in episode 32.
- Despite being twins, she became an elder before Kayden, in fact Kayden never became an elder.
