The Katephone Warehouse - Telegraph Kate Moss's collaboration with Carphone Warehouse poses many questions...and the answer to at least one of them is yes, she's looking good. And you thought it was just a plastic phone cover. But Kate Moss's latest collaboration - with Carphone Warehouse - provides plenty to mull over: Is this a signal that one of the modelling world's all time greats is playing an endgame and cashing in her chips while they still fetch a few million? Is this merely part of a Marc-Jacobs-for-Diet-Coke trend of cool celebritydom getting down and dirty with the mass market and emerging unscathed to fight another day and flog us something else when they're 80? Will these link-ups with ubiquity-products eventually destroy Moss's mystique? Will we have forgotten all about it by next week? Rolling Stones for Microsoft any one?

She revealed at a lunch launch at The Ivy today that she's already working on her second Katephone Warehouse collection. "The next one's going to have all these chains with charms on that you can attach to your phone," she told me.

"You need one of these cases," she said, eyeing the dog-eared dog ears on mine - she would have been a brilliant sales assistant in another life. I explained that I could never ditch my current model, not even for the mock-croc one based on her favourite Dunhill lighter, because it had been lovingly chosen by my daughters. She looked unabashed. They only chose that one because there's no mummy choice out there. READ: Kate Moss gives blessing to tell-all Primrose Hill set documentary Actually, she's not wrong. Apart from those chic-but-serious Pantone cases, this is an extraordinarily underexplored market, currently filled with the kitsch and the 'ironic'. So perhaps Moss is being shrewd with this latest collaboration. There's nothing to dislike about the black iPad cases either, even though their little anchor motif, based on her tattoo is not a million miles from J.W. Anderson's motif. They're plain, black and classic - rather like the chic 1950s style knee-length Prada dress she was wearing. But not quite. (Accessorised incidentally, with strappy neon Louboutins and a gorgeous tan. Yes, she looks good.) Kate Moss on the phone earlier today, with one of her black and silver designs.

Her ten-year-old daughter Lila Grace however won't be getting one just yet. "She has an iPod touch," her mother revealed. But a phone? She's way too young for that.
