Jennifer Saunders steals the show as she turns on Stella McCartney’s crimbo lights...

 The Stella McCartney annual Christmas light switch on is always a predictably starry affair where a group of celebrities come together to bask in their collective brilliance for an hour or so.

So this year Stella decided to spice proceedings up a little by inviting her pal Jennifer Saunders to the bash in the guise of her Ab Fab character Eddie.

She apparently made jokes about the celebs in the crowd – including Kate Moss and Stella’s dad Paul McCartney – as she switched on the shop’s (really quite naff) festive lights with Emma Bunton.

Ab Fab will also be returning to our TV screens this Christmas.
