In tonight's first heat TV presenters Donna Air and Alexis Conran, YouTube vlogger Marcus Butler, Singer and X Factor regular Sinitta, and comedian Tommy Cannon are hoping to impress.
The first challenge is the mystery box, which contains ingredients with a Mediterranean theme. They'll then take on the task of cooking in a restaurant kitchen, before heading back to MasterChef HQ to prepare a two-course meal of their own design.
One of them will be going home tonight before this heat continues on Friday. Who will be unlucky?
Celebrity MasterChef, BBC1, 8pm
