Her rear has won the world over but now another rear of hers is making headlines. Pictures have emerged showing the back of Pippa Middleton’s car being clamped.

Witnesses claim the 27-year-old’s $60,000 BMW Z4 soft-top was immobilised by authorities in a street in London’s fashionable Chelsea, where she had a flat, presumably during a shopping spree.

Surely, having your Z4 clamped would make anyone distressed but luckily for the royal sister-in-law she has a new car waiting for her.

It’s reported that Pippa’s security is a concern for her parents so they are replacing her (clamped) BMW Z4 with an armoured car.

Millionaires Michael, 61, and Carole Middleton, 55, want to buy Pippa a $ 142,608 bomb-proof Audi or BMW according to UK publication The Sun.

A source told the paper: “Carole and Michael have taken a raft of measures following advice from one of William's most trusted bodyguards.

“Pippa's car will have all the latest security devices, including armour plating. It will be bomb proof.”
