The familiar faces of John Torode and his Masterchef partner-in-crime Gregg Wallace return this week for the 13th season of Celebrity Masterchef, pitting 20 famous faces from TV, sports and the music industry against each other in a culinary competition like none other. In the first of the four heats we see five celebrities go head-to-head with one another for their chance to take one of four places moving forward in the competition. Among the famous faces today are former rugby star Martin Bayfield, Union J's Josh Cuthbert and Keith Allen while, rounding off the first heat, Michelle Ackerly and Carol Decker try their hands at cooking. The five would-be chefs first come up against the mystery box challenge before they are whisked off to cook in two of London's busiest restaurants. Finally the chefs must design and prepare a two-course meal within an hour in a climax which will see one contestant taking an early ride home. Celebrity Masterchef - Thursday 8:00pm on BBC 1.
