X Factor bosses are said to be furious after a pregnancy testing kit was discovered in the house the female contestants share.

A researcher reportedly found the test, which could belong to a singer on the show or a crew member, in a communal room at the Hampstead mansion.

"Bosses went mad when told about the find because they have a duty of care towards the contestants and staff during their stay because of their relatively young ages," an X Factor insider told The People.

Simon Cowell was immediately informed of the find and the unnamed owner has since been discovered.

"After an investigation was launched the female who owned the kit sheepishly came forward and admitted it was hers," said the source.

"The words 'pregnancy' and 'X Factor' just don't sit well together. It's meant to be a family show and bosses will go to any length to protect that image."
