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

The Great Celebrity Bake Off for Stand Up To Cancer continues, as more celebrities enter Britain's most famous tent to 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 journalist and presenter Stacey Dooley, Little Mix's Jade Thirlwall, internet personality KSI and comedian Katherine Ryan into the nation's favourite tent.

In three challenges set by judges Prue Leith and Paul Hollywood, the celebrity bakers make cocktail flavoured fondant fancies in the Signature and have their pastry skills tested in the Technical, before creating a showstopping scene showing the judges something they can't live without, all from biscuit and meringue.

Celebrity Bake Off continues Tuesday at 8pm on Channel 4.
