But it wasn't "toilet-gate" or the cheating itself that had viewers upset, but rather Stacey's anger at Hayley for "taking advantage" of her "vulnerable" husband Michael. While Michael continued to deny that there was no kiss whatsoever, Hayley admitted to kissing David after the night out.
"It's his word against hers, who's lying?" Stacey told the camera. "Michael is genuinely a good guy and I can never take that away from him. He would move mountains for me, like I can't just forget that glimmer of hope."
"I am disappointed at Michael but he's also heartbroken as well, we're both left heartbroken. Why can she walk away smiling? How dare she get away with this."
But fans were left angered when Stacey decided to use the dinner party to yell at Hayley for ruining her marriage.
"Why were you even out with my husband alone? You've just ruined a relationship, yes he's a d*ckhead and he parties but you've taken that for granted. You were encouraging vulnerable Michael," Stacey said at the dinner table.
