'Big Brother' has welcomed back former housemates Alex Sibley and Adele Roberts, who starred in the 2002 series, as part of a new task.
The pair, who starred alongside Jade Goody and Kate Lawler in the third series of 'Big Brother', were sent into the house to take on Kara-Louise and Brian in a series of sporting challenges as part of the shopping budget task.
The 'Big Brother' house was also altered to resemble the 2002 house, with plastic bars dividing the rich side of the house from the poor side.
When he entered the newly-designed room, Brian said: "It's Big Brother Three, Big Brother Three, dude."
Brian then asked Kara-Louise if she was going to strip naked like Jade Goody did in the third series of 'Big Brother'. She replied: "I'll leave that to you."
Brian and Kara-Louise were then introduced to Alex and Adele.
Alex said to the housemates: "You'll have days when you're really good friends with people, and when you're in such a small space like this, you fight over simple things."
Adele said: "Don't be scared. It's OK when people boo you. You'll get over it."
The current housemates won the basketball challenge before Alex and Adele levelled the score in the darts contest and excelled at the football keep-ups, meaning a win for the former contestants.
Later in the night, Brian revealed his true feelings for Amanda by declaring: "I love you".
He said: "You're so nice, you've always been nice to everyone. You're so modest, and you never take any of this on board. That makes you even better."
Meanwhile, twins Sam and Amanda have won the right to be nominated as one person but were then automatically put up for eviction. They face the public vote this week with new housemates Kara-Louise and Jonty.
