Brian is the latest Big Brother housemate to be celebrating his birthday in the house – and he is leaving those teenage years behind.

The Basildon boy turns 20 on Tuesday – but was so engrossed in a late-night conversation in the caravan that he failed to realise the big day had arrived – until Sam reminded him.

However, his celebrations were quickly muted as he realised he was now in his twenties. “I’m not a teenager no more!” he shrieked. “I want to be a teenager forever!”

The housemates, meanwhile, have been planning to celebrate in style, with Carole making the birthday boy a surprise cake.

“I’ve bought blue food colouring, I’ve got icing sugar and I’ve got a plastic bag down there,” she told Tracey on Tuesday morning. “I’m going to make an icing bag.”

Tracey was quick to question how Carole planned to get Brian out of the house, but she had that all worked out. “The girls are taking him to the caravan,” she said. “He’s going on a day trip.”

The Big Brother housemates have performed a one-off episode of an Australian soap opera as part of their task to welcome new arrival ‘Pauline’.

They were given their roles on Monday evening for the soap, entitled Housemates, while a special set was constructed in the living area where the performance took place.

And every housemate had their own stereotypical Aussie character name, with ‘Pauline’ playing sexy girl next door Kyleen and Liam starring as her love interest Goldfish.

Meanwhile Ziggy took the role of surfer dude Brandon, the twins played fun-loving twins Sandra and Sheila, and Carole appeared as Janine, the geek in need of a makeover. And Charley was cast as Dingo the dog.

The housemates were given one hour to get into character before the performance – but not all of them were happy with the casting, with Charley calling her canine role “humiliating”.

Nonetheless, they successfully completed the episode – and afterwards decided they liked the set so much that they wanted it to stay. “We’ll have to ask them if we can keep that living-room,” Carole said.
