She has visited his offices in London and they are thrashing out the details."Green - who owns the Arcadia group, which includes Topshop - is said to be particularly keen to secure a range by Christina as he believes it would compliment Kate's well.The source added to Britain's the Sunday Mirror newspaper: "Philip loves her style and believes she would add something new to Topshop. Christina is the blonde bombshell who is into pop whereas Kate is the rock chick and model. She'd appeal to a younger shopper than Kate."Kate recently extended her contract with the store for another three years, and revealed she can't wait to start work on her new lines.She said: "The last two years have been an exciting experience and Topshop has given me the perfect platform to develop my own collection, which is something that I have wanted to do for a long time.
