PREVIEW: Celebrity Bake Off (Episode 3), Channel 4

Four more celebrities put their baking skills to the test and inspire viewers to do the same and raise awareness for Stand Up To Cancer.

Matt Lucas welcomes MC Dizzee Rascal, radio DJ Nick Grimshaw, psychiatrist and author Philippa Perry and comedian Reece Shearsmith to Britain's most famous tent.

In a bid to impress judges Paul Hollywood and Prue Leith, the bakers make vegetable slices for their Signature challenge, attempt a right royal Technical and bake a 'selfie' of themselves at work made entirely from biscuit for their Showstopper.

Celebrity Bake Off for Stand Up To Cancer continues Tuesday at 8pm on Channel 4.
