While some viewers, including our columnist Nicola McLean, have thought Stevi could be tiring of Chloe, in a speech to the housemates last night he said that couldn't be further from the truth.
In a group toast on the final night, the singer said: "Me and Chlo were asked to do this as a couple and I had a lot of doubts. It's a big risk. It could either make or break your relationship but you know what for me I thought it would break us but it has made us a lot lot stronger."
Turning to his fiancee, he said: "I just love you more and more each day. I wake up next to you, even the smell of our breaths don't matter, even without the make-up and all the glitz and glam of you. I just love waking up to you and I just can't wait until I get married to you and hopefully have a little bubba."
The couple met on X Factor last year and became engaged before entering the house.
Their relationship has been tested on the show during challenges, most memorably when they had to sacrifice their PDAs and Chloe's engagement ring, leaving Chloe in floods of tears.
Chloe and Stevi - who represent one housemate - will face Sherrie Hewson, Bobby Davro, Austin Armacost, James Hill and Natasha Hamilton in the final.
CBB's finale airs at 9pm on Channel 5.
