Stephen Bear's plan to marry girlfriend Lillie Lexie Gregg has been scuppered after she broke up with him in the Celebrity Big Brother house over his fling with Chloe Khan.
Family and friends of the housemates are sent into the compound in Thursday night's show to distract them from completing challenges in a task.
But Ex On The Beach star Bear is interrupted by Lillie Lexie - who he was still dating when he entered the house - while trying to balance three doughnuts on his head.
"Hi, I was Stephen's girlfriend," she says as she introduces herself to the house as he looks on shocked.
He remains silent as she tearfully addresses him, saying: "This is the hardest thing I've ever had to do, I just needed to see you... it's so surreal... I'm having to watch this from home.
"You had me with you until the car came to collect you; you left me with your family. You asked me to be there when you got home, I was supporting you 100%.
"The embarrassment and humiliation I've had... this is all one big game to you, it is a joke at my expense."
Later in the Diary Room, viewers will see Bear break down in tears but admit she had a "lucky escape".
He says: "In the long run she would have got hurt a lot more... I would have married her.
"I think about her every day. I can't be with her; it's not fair on her.
"I was adamant I wasn't going to get with no one. Everything happens for a reason... She's had a lucky escape from me.
"It took me 26 years to find someone I care about."
Bear confirms to Lewis Bloor and Marnie Simpson that he was in a relationship with Lillie Lexie before he entered the house.
"She's made me look really stupid and bad," he fumed.
Later he has a conversation with Ricky Norwood in which he admits that he wants to see Playboy model Chloe again when he leaves the house.
During the task, Samantha Fox is visited by her mother, Aubrey O'Day receives a video message from Jersey Shore star boyfriend Pauly D and Marnie is greeted by her Geordie Shore co-star and cousin Sophie Kasaei.
Sophie tells her she is proud and insists that the romance between Marnie and Lewis is not a "showmance".
"Whatever is going on between them, it's real!" she states.
