Here is Pippa Middleton walking round a cold and wet London, but still wearing her shades – she really has turned into a true celebrity now. She doesn’t go anywhere without wearing her sunglasses – whatever the weather. Pippa has had a crazy year since being a bridesmaid for her big sister Kate. Newly single Pippa was also spotted recently having a cosy dinner with her ex. She spilt up with her long term boyfriend Alex only weeks ago, but was seen the other night having dinner with another ex who she dated for 3 years before Alex. Pippa and JJ Jardine Paterson met at university in Edinburgh, and dated after that. It was on Friday night that they dined together with an intimate meal in a private dining area at a hotel restaurant. A source said: "Pippa looked really happy and relaxed in a striking orange blouse. It is clear they have history. They seemed keen to keep themselves to themselves." After they had finished dinner, they were then joined by friends, but when it came to leaving, they left together. And then on Saturday they both attended the wedding of a mutual friend. That’s seeing the ex twice in 2 days. Hmmm.... fishy. Pippa is said to have split recently with Alex because he struggled to deal with the attention she was getting from the world – maybe JJ will handle it better? A source close to Pippa talked about her and JJ and said: "They've remained good friends and now she's single again we wouldn't rule it out. JJ ticks all the right boxes — he's good-looking, sporty, and is from a wealthy family." It has been revealed recently that Pippa is to write a book – a book on how to throw the perfect party. She is said to be working hard on it.
