Bill Cosby is being sued by CitiMortgage for allegedly defaulting on a $4.2 million loan tied to his Lenox Hill townhouse. The lawsuit claims the Cosbys owe $3.7 million in principal, along with significant interest and fees. Purchased in the 1980s for $327,000, the property served as a second home, though it's unclear if Cosby ever lived there. This financial dispute adds to Cosby’s history of legal and personal controversies. The townhouse faces the risk of foreclosure as the case unfolds.
