You'd have to have been living under a rock for the past few weeks to not know about Karl Lagerfeld's collaboration with Diet Coke since it transpired that he lost a lot of weight by sticking to a diet of vegetables and Diet Coke.
The new designs of the bottles popped up on the internet a few weeks ago, but now the official campaigns have emerged. Uncle Karl went to none other than Paris to officially launch the product, with a very gorgeous Lily Cole offering her moral support. We are glad to see her back to her natural hair colour too - very bright and fitting for summer.
