Kate Moss is preparing to make her big screen debut in Ab Fab: The Movie. British actress Jennifer Saunders confirmed that the 41-year-old supermodel is set to appear as herself in the movie version of the award-winning 1990s BBC comedy series Absolutely Fabulous. The hit show followed the boozy lives of characters Eddie Monsoon – played by the show's writer Saunders – and Patsy Stone (Joanna Lumley) who worked in fashion and PR.

"I can confirm Kate does have a part. It's not yet decided whether she'll have a speaking part, but she'll definitely be in it," she told the Daily Mirror.

Considering Moss appeared in the series in 2012, Saunders said that the casting was a "no-brainer". "She's a big fan of the show and we're pals, so aside from the fact she's the definitive model, it was a no-brainer. There'll also be a bit of Spice with Emma Bunton and Lulu. I've only just got the green light so I'm tweaking the script and I'm trying not to over-egg it."

Meanwhile, sources close to the project have revealed that Victoria Beckham is also tipped to make a cameo. An insider told The Sun newspaper: "Jennifer is desperate to keep things under wraps, but landing Posh will be a big coup."

Producers have also cast Saffy's daughter: a 13-year-old girl who is "self-assured and cool, and naturally finds her mother embarrassing, but her granny amuses her".

Filming is expected to star during London Fashion Week with the film hitting cinemas in 2016. Saunders' Ab Fab co-creator and writing partner Dawn French is also set to make an appearance in the film.
