Scott Mills, a contestant on Celebrity Race Across The World, temporarily halted filming due to severe headaches he initially feared were caused by dengue fever. After three days of debilitating symptoms, it was revealed by his partner, Sam Vaughan, that the issue stemmed from caffeine withdrawal, as Mills had not consumed coffee during their travels in South America. The couple faced budget strains because of Mills' coffee dependency, which was a source of contention while competing against other celebrity pairs. Mills shared that the experience was challenging due to high temperatures and language barriers as they journeyed from Brazil to Chile. The first episode premiered recently, showcasing their adventure alongside stars like Kelly Brook and Jeff Brazier. Mills and Vaughan tied the knot in June, shortly after completing the filming.
