Earlier today, Big Brother told Amanda that she had won yesterday's Channel Task by swimming the furthest out of all her fellow housemates, clocking up a whopping 6.5km in the outdoor pool.

"Wow, really? Go me!" the twin squealed. "This is the best ever, I have never won anything before!"

But she wasn't so happy when Big Brother revealed that her prize would be to choose all of the items on this week's shopping list.

"How is that a reward?" the blonde asked, perplexed. "I feel I am being a little punished!"

She was even less pleased when Big Brother told her she would have to stay in the Diary Room for an hour and complete the list herself.

"Are you lying, Big Brother?" Amanda wailed. "I can't add up - I don't even know how to spell! Will you add up for me?"

When Big Brother refused, the twin was forced to attempt to add the items up herself. At first she got into a muddle, muttering "I don't understand", but eventually Amanda beamed and exclaimed, "I didn't realise I was that good at maths!"

With just ten minutes left on the clock, the blonde began to panic. "Big Brother, please give me more time - I will be your best friend!"

The shopping list was finally submitted - but will the housemates be Amanda's best friend when they discover what they'll be eating for the next week?
