Andrew entered the 2007 Big Brother house as part of the 'secret couple'. His girlfriend of twelve months, Hayley, was also in the house. Their mission given to them by producers was to keep their relationship a secret for two weeks, after which time, they would be outed by Big Brother. If they failed to keep their relationship unknown, one of them would face eviction. Hayley's ex-boyfriend, Billy, was also sent into the house, surprising her as she had no prior knowledge of the event. Hayley and Andrew passed their challenge and won $50,000 to add to the final prize money.
