Cher and Aiden, who are both already among the bookies' favourites to win the show, reportedly grew rather close at boot camp, despite strict orders from Simon Cowell that there shouldn't be any funny business.
An insider said that the pair are trying to keep their relationship under wraps but have failed to hide it from other contestants.
The source told the
Daily Mirror: 'Simon has laid down the law' about romances between the reality show hopefuls, including rules about no girls being allowed in the boys' rooms after dark and vice versa.
'He made it very clear no one is bigger than the show and everyone is expendable, so if they break the rules they are out.'
Despite the fact the live shows haven't even started yet, Cher has already hit the headlines a number of times.
The 17-year-old wowed the judges with her rendition of Turn My Swag On by Soulja Boy - a performance which led rapper Tinie Tempah to describe her as 'representative of youth culture today.'
