The housemates were tasked with recreating one of Marco Pierre White's signature dishes after the chef entered the house earlier today.
Working in pairs, the celebrities had just 30 minutes to cook sea bass with chinoise sauce after a brief lesson, before White tasted the dishes to determine the winners.
Tara Reid and Lucien Laviscount triumphed in the cooking challenge and were crowned Big Brother's Best Chefs. They will be rewarded with a lavish private dinner for two later this evening.
However, Jedward failed to impress White with their culinary skills and will have to wash all the dishes from the task as punishment. The chef did however note the twins' enthusiasm.
Celebrity Big Brother host Brian Dowling recently described Jedward as a "reality TV dream".
