Loos became the personal assistant to former England national football team captain David Beckham, when he transferred to Real Madrid in July 2003. Her employment was terminated a few months later and Loos subsequently gave an interview to the British tabloid newspaper "News of the World" in April 2004, alleging that she and Beckham had conducted a four-month affair whilst he was married to his wife Victoria. The claims were never corroborated and were dismissed by Beckham as "ludicrous", although he did not mount a legal challenge to the story.
