The stars competed in a task yesterday which would grant two housemates, or John and Edward as a pair, total control of the food for the upcoming week.
The duo triumphed in 'Stuck In The Lidl With You' after beating Bobby Sabel and Kerry Katona in the final round of the task. Late last night, Big Brother informed the Grimes brothers that they would be leaving the house to go to a supermarket.
Emerging from the Diary Room, they excitedly informed their fellow housemates of the twist. "We're going to a real shop. Me and John are going to a shop right now," Edward explained.
Kerry Katona proceeded to list items the twins needed to remember to purchase, including beans, pasta, tuna and toilet roll.
The 19-year-olds expressed their joy at being allowed to return to the "outside world", before trying to decide which jackets they would wear for their trip.
At the supermarket, each twin was given two and a half minutes each to dash around the store and collect as much as they could. John collected £303.46 worth of shopping, with items such as 41lb of bananas, 11 large jars of coffee, two legs of frozen lamb & a lot of sweets.
Taking the total shop to £503.94, Edward collected £200.48 worth of shopping including 16 boxes of organic eggs, 17 boxes of blueberries and ten punnets of red grapes. Jedward then returned to the house to show the sleeping housemates how they had got on.
Celebrity Big Brother continues tonight, with the third live eviction, at 9pm on Channel 5.
