The rumour mill has been working over time this week about a certain possible cameo appearance in Gossip Girl. The cast have been filming in Paris recently gaining much media attention thanks to the amazing wardrobe. Leighton Meester and Blake Lively have both been spotted in a range of chic ensembles, but what could be more chic than hanging out with Karl Lagerfeld? Blake was spotted taking part in a photoshoot for US Vogue at the Ritz alongside Mr. Lagerfeld, but did she manage to persuade him to appear in an episode? I am so excited about this possibility that I've already started imagining how he might fit in to the storyline! Would you like to see Karl appear in an episode of Gossip Girl?
