Pippa Middleton was amongst the biggest celebrity names at day three of the Cheltenham Festival this week. The sister of the Duchess of Cambridge, Pippa opted or a Katherine Hooker London coat and a brown fur Cossack for an afternoon of racing in chilly temperatures at the Gloucestershire course.

According to the Telegraph, Miss Middleton's coat can only be purchased custom for £815, while her Kate Spade clutch-bag carries a price tag of £219. Russian style Cossack hats were a major trend at Cheltenham's ladies day, where there is no dress code. Many festival goers tweeted about spotting Middleton around the course. Anthony Ward weirdly wrote, "Just filmed Pippa Middleton watching the first race from balcony of private box. She looked pretty happy with the result," while Mark Connolly said, "Just in the bet victor tent, pippa Middleton just walked past.. Never seen as many police around one person."

Gina Bryce assumed she had become an overnight celebrity for a short time, tweeting, "Wondered why the photographers were going wild...I was walking in front of Pippa Middleton! Oops!! #scrum" Middleton arrived at Cheltenham with former banker Tom Kingston, whom she is not thought to be dating. Kingston is often seen accompanying Pippa to various public events.

Elsewhere at day three of the world's biggest racing festival, Irish actor James Nesbitt was seen wandering around the betting ring wearing a tweed jack, wayfarer sunglasses and a Manchester United scarf. The actor - who smoked a couple of cigarettes - is the co-owner of horse Riverside Theatre, who was unable to regain his Rynair Chase crown, being beaten by a classy Cue Card, for the Tizzard yard.
