We totally forgot ahead of the launch show that Emma would know David quite well, as David appeared on I'm A Celebrity... Get Me Out Of Here! alongside Emma's husband Matt back in 2006.
Speaking on BOTS last night, she said: "I hadn't seen David for so many years. For two years, David was very much part of our household. Him and Matt were attached at the hip for a long time after they came out of the jungle together, so I've spent a lot of time with David.
"He is truly bonkers. He's an absolute nutcase but deep down he has a heart of gold so I hope he does well."
Emma also suggested Darren Day could be one to watch...
"Keep your eye on Darren. I think he will go far. We haven't seen him for so many years, have we? We know of his reputation from years ago and he just, I don't know, he seems like a real gent. I don't know him, I'm just making assumptions from meeting him for 30 seconds, but I think he'll do quite well."
CBB airs nightly on Channel 5.
