The Ab Fab movie is like that party everyone wants an invite to.

This month we learnt that Kate Moss, Joan Collins and a host of other stars are on board for appearances, cameos and parts central to the plot.

Cara Delevigne is said to play a role in a party scene, Rebel Wilson approached Jennifer Saunders in person to bag a role and even Victoria Beckham is tipped to be involved in the flick.

With the rumour mill running high, we take a look at everything we know so far about Edina (played by Saunders) and Patsy's (Joanna Lumley) next installment.

It's not called Ab Fab

Early this year Jennifer Saunders confirmed the film will be called Edina and Patsy after the TV shows' main characters. However, stars are continuing to use the hashtag #AbFabMovie and the official twitter account goes by the same name - @abfabmovie.

Kate Moss meets a tragic fate

Last month, Kate Moss was spotted gliding through the River Thames in a sparkly green dress with a cigarette in one hand and champagne glass in the other. What looked like the aftermath of a wild party turned out to be Moss filming her scene in the Ab Fab film.

It's thought that in the film, Moss' character goes missing during a fashion soiree, sparking fears she has been killed. Pictures of a faux shrine set up along the banks of the river in memory of her also emerged.

Watch Moss glamorously stride across and out of the Thames on YouTube.
