Lucy In Disguise - FrostFrench. Lily Allen and her sister Sarah Owen bare a striking resemblance to Sadie Frost and Jemima French. FYI - Watch Lily and Sarah try and make it with there new business venture on Channel 4 tonight at 10pm. In Lily's own words she's 'deluded' - lets hope they are more of a success in fashion than their look-a-like counterparts' well documented business struggles, but I think its safe to say so far not so good. However I'm very interested to see how this turns out especially as Mary Portas has decided to be their consultant. The retail guru, is on hand - but for how long? Not sure she was too keen on the new business women's 'nice idea'. I'm hoping the title 'Lily Allen: From Riches to Rags' means just that and is not also a metaphor. I can't wait to tune in to find out.
