In scenes set to air on tonight's (4 July) edition of the Channel 5 reality show, the couple have an emotional reunion when Andy's partner Ed enters the compound as part of a task.
Upon seeing his boyfriend, a tearful Andy says to Ed, "Will you marry me?", but it seems he is one step ahead.
Pulling out a ring and getting down on bended knee, Ed announces: "I can do one better."
As Ed tries calm Andy down, he says: "Come on, look at me. Put your hands down. Will you marry me?" to which he responds through tears: "I will, I will. of course I will."
He adds: "I'm so lucky. I knew it before, but since being in here, I can't live without you."
'Big Brother' host Emma Willis teased their arrival in the house during Friday's live eviction, indicating that one or two of the guests may be sticking around for a while.
