DANIEL O'Reilly proposed to his girlfriend Shelley Rae Live on tonight's CBB.
The comedian, better known as Dapper Laughs, popped the question after becoming the third contestant to leave tonight.
During his exit interview with Emma Willis, Daniel, 33, turned to his girlfriend, 27, and said: "When I was in the house, every day I was regretting that I've never asked you this so, will you marry me?"
He added: "Sorry about the ring, Ginuwine made it for me. We'll trade it in for better paper."
Shelley – who recently gave birth to the couple's first child, a baby girl called Neve – was overcome with emotion and sobbed into Daniel's jacket as he kept a tight hold of her throughout the rest of the interview.
He added: "I'll double check with your dad afterwards if that's OK."
"Shelley was lost for words and broke down in tears.
"Ahhhhh the proposal and the ring 😭 #CBB.
"Aww that was so lovely congratulations to @IRaeOfSunshine and @dapperlaughs #cbb #CBBDaniel
@dapperlaughs that was such an amazing and beautiful thing to do.. 💓 congratulations to you and @IRaeOfSunshine 🤵💓👰 #bigbrotherwedding #CBBDaniel #CBB.
"I don’t like Daniel but I find it ADORABLE that this time away from his girlfriend made he realise he never wanted to be away from her again #cbb."
Hugging her, Daniel asked his fiancé: "Is the ring alright, you won't need another one will you?"
In CBBBOTS Dan revealed how the ring was made.
He explained: "He said wait right there, I'll be back in a minute and he came back and he made the ring.
"Courtney came in and said it's not glamorous enough, add a couple of crystals and she's signed up for life."
The comedian is known for his laddy brand of humour, but earlier this month Shelley insisted underneath his on-stage bravado Daniel is "sensitive, caring and passionate."
Speaking to The Sun Online, she said: "He's amazing. He absolutely adores children. He's so good with Neve, he's so hands on. He's always up early in the morning and bring Neve down and make breakfast just so I can have an extra hour in bed."
