Chelsea was the 16-year old niece of Matt Fielding, who became her guardian once her father, Luke, died in a plane accident. Her mother, Denise Fielding, had abandoned her when she was younger, leaving Chelsea no place to live. After Matt agreed to return her to Constance, Chelsea ran away from home. She later showed up at a shelter, where Matt and Samantha Reilly went to see her and brought her home to stay with Matt. Later, Chelsea's mother showed up and wanted to take Chelsea to live in Europe with her, but Matt wasn't keen on that idea, though Chelsea wanted to live with her.
