They will first tackle the Mystery Box challenge, during which they will prove they can serve up a dish based on surprise ingredients, before being thrown into hot water in a professional kitchen.

Upon their return to the MasterChef studio, the five celebrities must then prepare a two-course meal for the judges before one of them is sent home.

The winner of the series will join the ranks of previous Celebrity MasterChef champions, including Kimberly Wyatt, Lisa Faulkner, Ade Edmondson, Sophie Thompson and Emma Kennedy.
