'X Factor' hopefuls Emily Middlemas and Ryan Lawrie have reportedly resorted to having sex on the stairs of the show's £3.6million house after they were banned from sharing a room.
The couple - who have been together nine months but have known each other for four years - have been having sneaky late-night trysts while the other contestants get some shut eye after bosses refused to let them have their own bedroom.
A source told The Sun newspaper: "Emily and Ryan have been getting frisky on the stairs late at night. They're banned from going in each other's rooms so have found a way to bend the rules and head to the stairs for their hook ups instead when they think all the other contestants are asleep.
"And it's not just at night when they're all over each other. Ryan can't keep his hands off Emily and they're always kissing and cuddling in the house and during rehearsals - it's creating an uncomfortable atmosphere for the finalists. The rest of the contestants have this theory that if they keep going at the rate they are it's going to harm their chances in the competition."
And it seems the couple - who are both from Scotland - are taking their romance very seriously and are even thinking about getting married and starting a family with one another.
Ryan said: "We are pretty serious, yes. I would like to think she is the girl I am going to marry and have children with one day."
Emily, 18, is currently being mentored by Simon Cowell in the Girls category, while Ryan, 20, is in Nicole Scherzinger's Boys section after she brought him back as her Wild Card choice.
