Former EastEnders actress Hannah Waterman, music impresario David Gest, TV gardener Diarmuid Gavin and Loose Women presenter Sherrie Hewson host Christmas parties for each other in this festive special of the wining and dining challenge. Highlights include live reindeer, excruciating celebrity rapping, rancid eggnog, plastic surgery revelations and starving guests nipping out for a pizza - before one of them walks away with £1,000 for their favourite charity. At 8.30pm, you can either switch to RTE1 for Corrigan's Live Christmas Cook-Along (Mary Kennedy presents as Richard Corrigan concludes his attempt to prepare the perfect Christmas dinner in real time). Or you can stick with Channel 4 for a festive edition of Gordon Ramsay's Christmas F Word at .9.00pm. 'Cause that's what Christmas is all about: the best way to stuff one's face.
