Jedward created chaos in the Celebrity Big Brother house as they ran amok as "punks", angering other contestants.
The pair threw chairs into the pool, flipped mattresses in the bedroom, and tossed soup around the kitchen during their rampage.
The Grimes twins' behaviour was blasted by housemates, with Paddy Doherty ranting in the diary room and Kerry Katona calling them a "pair of numpties".
Jedward - dressed in black - hatched their plan for mayhem at lunchtime, telling Big Brother they were going to be "rebellious" punks and were "not going to take any rubbish from anyone".
After a pillow fight, they dumped items in the pool and then headed into the bedroom where Amy Childs and Darryn Lyons were asleep. John and Edward woke them as they flipped mattresses in the air.
Amy grumbled: "They don't have any respect for anything."
They then moved on to the kitchen, fighting with washing-up liquid and soup.
Kerry ordered the duo to tidy up the mess they had created, while Paddy exploded in the diary room following the trail of destruction. He branded the pair "sausages".
Later in the afternoon the twins sheepishly began to clear the mess as the house got back to normal.
