Bjorn Borg's first wife, Mariana Simionescu—a former top-30 Romanian professional tennis player and Wimbledon junior champion—was a central figure in his life during his peak championship years. The couple married in 1980 following a high-profile romance, but their marriage ultimately ended in a quiet divorce in 1984 after he stepped away from competitive tennis. Following their separation, Simionescu chose to remain living in Monaco, where they had shared their principal residence during his playing career. She did not remarry for many years, dedicating her life to her family and personal pursuits while maintaining fond memories of their storied era together, and she has frequently spoken to the media with warmth and empathy regarding her historical chapter as part of tennis royalty.
