As the singers, who met on the ITV talent show last year, are now cooped up in the compound, they will miss this weekend's launch of the new X Factor series.
"We are devastated, especially Steven, who absolutely idolises Simon Cowell," said Chloe.
"I think that is the worst part about going into the CBB house, that we will miss The X Factor. It's all on record though isn't it? We can catch up when we leave."
But, hey, Stevi can see the silver lining if they get kicked out of CBB early: "We might only survive three or four nights and be out in time!"
Friendship blossomed between the singers when they both made lives shows on the last series of X Factor. That friendship turned to romance which became an engagement last month.
CBB airs nightly on Channel 5
