Celebrity MasterChef returns, with 20 familiar faces from the world of show business and music, all wanting to follow in the footsteps of last year's champion, Sophie Thompson, and take the 2015 title.

In the first of the heats, the first batch of five celebrities undertake three tough culinary challenges in a bid to prove their cookery talent to judges John Torode and Gregg Wallace. Hoping to show they've got what it takes are former Girls Aloud singer Sarah Harding, singer and songwriter Chesney Hawkes, TV presenter Yvette Fielding, and actors Sheree Murphy and Patricia 'Tish' Potter.

The first challenge for the five hopefuls is the invention test, the infamous test of imagination and creativity. They must use the provided ingredients, including pork fillet, chicken wings, pears and dark chocolate, as well as a larder, to create just one dish - sweet or savoury. With nerves running high and just 50 minutes to create something from scratch, the celebrities must think on their feet to impress the judges.

The celebrities are then split into two groups to take on the challenge of cooking for the first time in a restaurant kitchen, preparing dishes for paying customers. Tish and Yvette head to Novikov, which specialises in Asian cuisine, while Chesney, Sheree and Sarah are sent to Sixty One. For both groups the cracks begin to appear as they fight to keep on top of customer orders, and for some the pressure is just too much.

In the final test of culinary creativity, it's back to the MasterChef headquarters as the contestants are asked to prepare a two-course menu of their own design. The celebrities work furiously in a last attempt to prove themselves to the judges, because at the end of this test one of them will be going home. Show less
