Throughout the day the housemates have received a series of treats, including breakfast served by Anthea Turner, haircuts by Lee Stafford and beauty treatments, make-up artist sessions and glamorous clothes to wear.
After enjoying a pre-dinner cocktail in the living room, Big Brother invited the housemates to the table for a specially cooked Thai meal.
Celebrity chef Nancy Lam greeted them in the kitchen, as each of the housemates kissed her and introduced themselves. Nancy started serving dinner while exchanging banter with the group. Placing a turkey toast starter on Mario's plate, the chef told him: "It's not cock on toast, it's turkey on toast!"
She then told the group: "You are the more boring, ugliest bunch that are left. But we like you!" Admiring JJ's diamond earrings, she asked: "Are they real?" He replied: "Nah, I can't afford real ones." Nancy quipped: "That's no good, I can't nick them!"
As JJ showed David how to use the corkscrew, Nancy laughed: "He doesn't know how to screw it in!" She then placed one of the main dishes on the table, saying: "Bisexual prawns! Or at least horny ones!"
The housemates gratefully tucked into a range of dishes, including noodles, basil chicken, spicy prawns and lobster. An excited JJ declared: "I've been wanting to try lobster for such a long time!" Nancy helped the boxer remove the meat from its shell, telling him: "Make sure you really chew it."
JJ suggested a toast, to which Josie said: "I think we should make this toast to Nancy, because that is quite possibly the best basil chicken I have ever had." Mario added: "And to everyone else who has been in the house, we'll see them all on Tuesday."
Nancy asked the housemates: "Are you going to have an exciting life after Tuesday?" They all replied yes, with JJ saying: "We don't know what it's going to bring yet." The chef advised the group: "What you aim for is what you get. You don't get what you want."
She went on to say: "This is one of my favourite programmes, I am very sad that it is finishing. People don't realise that this is part of life, how people live."
After serving individual chocolate cupcakes for dessert, Big Brother announced that it was time for Nancy to leave. While the group shouted: "No!" the chef began to throw water over them and laugh, before they all ran to hug her goodbye. As she reminded them not to forget the opportunities Big Brother had given them she headed to the store room, shouting behind her: "You all suck!"
"That meal was absolutely amazing," Josie said, while everyone agreed. "That wasn't just the nicest meal in the house, that's one of the best meals I've ever tasted," Mario added.
