Sophie and Kris's romance moves up a level

Kris revealed to Sophie that Big Brother had been asking him about the seriousness of their relationship last night.

Housemates have been told that "fake romances will not be tolerated" this year.

After emerging from the Diary Room, Kris explained: "I told them we were past the trumping stage."

He added: "I said usually it takes around three months but in here it’s been three weeks. I said 'Sophie trumps all the time.'"

Sophie laughed and agreed. "Yes," she said. "I’ve just trumped in the bathroom with Sree."
