That whoppingly expensive bejwelled ice pick, the 'Jagger Dagger', designed by Jade Jagger, and worth a hefty £125,000, was unveiled last night in London. Encrusted in diamonds, sapphires and lapis lazuli, the pick is in collaboration with Belevedere Vodka, which sponsored the celeb-studded party at Automat.

The bash drew the likes of Alexa Chung, in a cute belted ensemble, Julien Macdonald and model Portia Freeman, who was dressed in a Luella 'Batman' vest (£65) and Luella 'Buttercup' ruffle skirt (£195). A "cheaper" version of the ice pick is available from Harrods, but what exactly you would do with it is anybody's guess.

Meanwhile, everyone is gabbing about Daisy Lowe and Mark Ronson, who stepped out together for the first time as a couple at Jagger's party.

Yes, I am very jels...
