The former glamour model has teamed up with CRi-8 to create designs in three colours for several different versions of the music playing device.
The collection - which will be sold exclusively through the brunette beauty`s websites from Friday (20.08.10) - features five laser-cut designs in pink, purple and silver for the Nano, three for the Shuffle in pink and silver and two for the i-Touch, which are both in silver.
Katie said: "I`m really excited about my iPod range and love the way they have turned out. Being involved in the design process was fantastic and really gave me the opportunity to develop and create exactly what I wanted. Hopefully this is just the beginning and you will be seeing more from my Boutique range."
The iPods are the latest venture for Katie, who has amassed a £10 million fortune through ventures including modelling, reality TV shows, books, bed linen and equestrian clothing.
