Michael admitted to producers, 'Is KC good looking? Yeah, sure, she’s good looking. Never the less, Stacey has spoken, so I’ll be on my best behaviour, obviously.'
The the former Pussycat Doll then went over to meet the other newlyweds.
'KC came over and sort of sat between me and Stacey,' he explained. 'Hey, big move, girl!'
Michael gave viewers a little more running commentary. 'Stacey didn’t really welcome KC that well… she was welcomed kind of like a fart in a space suit.'
KC quizzed Stacey, commenting that she doesn't 'seem happy.'
'I am happy,' Stacey replied, monotone.
The experts then gave their two cents.
John: 'Stacey might be worried.'
Mel: 'Michael has strayed once!'
'Stacey's energy was really cold,' KC said. 'I haven't done anything!'
Then Stacey's attention turned to Elizabeth Sobinoff, who entered the room with her new husband Seb Guilhaus.
'I'm stunned,' she said to producers. 'Like, what are you doing back?'
Laughing to Connie and Michael, Stacey took a low blow, saying, 'She was one of the ones that was cheated on. And she was crying with the pizza box.'
A bit of empathy, hey, Stace?
