'I think tonight's going to be really interesting, we have two empty seats at the table so we have two new people who are going to be joining the group,' said Piper initially.
'I think everyone is a little scared and nervous on who these two people could be.'
As the guessing game continued, Port Pirie contestant Sal joked: 'Maybe it's going to be two celebrities? I want it to be Robbo from Home and Away!'
The potential Home and Away cameo proved to be a popular suggestion.
'I love him, I love Robbo! That would be amazing,' declared Veronica.
Sadly though, the group were later left somewhat disappointed when the mystery guest was a woman named Millie, who arrived without a partner.
She was shortly followed by stranger Carolina, who will create a group with her.
