Kate Moss is treating her upcoming third collection for Longchamp as her "baby".

The British supermodel is said to be involved in "every decision" of the designing process with the luxury French label.

Creative director Sophie de la Fontaine explained: "Kate has treated the third collection as her baby. She is a woman and wants Women to enjoy the bags as she would. I don't think people imagine how involved Kate is or how much thought she gives the details. She's involved in every decision."

The new line will feature a collection of "city living" canvas and leather shoulder bags, designed for everyday use in a host of military and safari shades, including khaki, cream and brown.

An entire weekend range will also be included in the collection, which was inspired by a trip the 36-year-old beauty took to stay at designer Mario Testino's house in Peru.

Sophie also revealed Longchamp is keen to collaborate for a fourth line with The Fashion icon.

She added to Vogue.co.uk: "Will there be a fourth collection? Of course! We hope so. We'd like it to go on forever as long as Kate wants it to."
