To answer directly: Prince Andrew was 41 years old when Virginia Giuffre (Virginia Roberts at the time) alleges they met in 2001. Context and details:

• Prince Andrew was born on February 19, 1960. This makes him 41 in 2001. Giuffre has described meeting him in 2001 and recounting subsequent interactions. The timeline places Andrew at 41 during that year, and Giuffre was 17 at the time of those alleged encounters, leading to intense media and legal scrutiny surrounding the case.
