It's time for the fourth and final heat week, which will see the last five celebrities of this year's competition take to the culinary stage. It's all to play for, as only the best three will make it into the quarter-final. The last group of celebrities taking a punt on winning the title are pop star, Mutya Buena, professional dancer and choreographer Vito Coppola, TV personality Diane Carson, BBC Radio 2 presenter OJ Borg and make-up artist and TV judge Dominic Skinner.
