The supermodel and Topshop boss Philip Green have decided to revive their partnership and a brand new collection with launch in April 2014.
"I have really missed being involved in the design process, and working with the team at Topshop," said Kate. "Now more than ever, with London being at the forefront of fashion…it feels like I’m back home working with Topshop."
Philip seems to be just as pleased with the news, saying, "I am personally thrilled that Kate wanted to come back to Topshop to work with us again.
"The first time around was such a lot of fun, and she has been sorely missed."
Kate and Philip are said to have decided to work together again whole on holiday in the South of France.
"Kate was talking about London as a style city, and how it was becoming ever more relevant on the international stage," said a source. "She's friends with Philip, so they said, 'Let's do it.'"
The details of the collection are firmly under wraps, but it is said to consist of around 40 pieces. Kate is said to be spending a few days a week working on it with Topshop creative director Kate Phelan and friend Katy England.
Kate's collaboration with the high street retailer first began in 2007. The duo had several sell-out collections before putting the partnership on hold in 2010.
