Billie Eilish has ended her professional relationship with agency mogul Casey Wasserman following allegations of his extramarital affairs, which have been described as a long-standing issue. Eilish's decision, finalized on August 15, 2024, came after a Daily Mail exposé highlighted Wasserman's behavior, leaving her 'very upset.' She and her brother, Finneas O’Connell, will now be represented by WME for all entertainment projects, consolidating their representation under one agency. The fallout from Wasserman's actions has raised ethical concerns about his leadership, particularly within the LA28 Olympic Games committee. Despite the scandal, Wasserman has not publicly commented on the allegations. Eilish's move reflects her desire to maintain professionalism and integrity in her career as she looks to new opportunities with WME.
