Pippa's pert rear-end helped catapult her to worldwide fame as she acted as maid of honour to sister Kate as she married Prince William.
Now parents Michael, 61, and mum Carole, 55, are looking at buying a £95,000 bomb-proof BMW or Audi to make sure she remains safe.
Unlike her sister Kate, 27-year-old Pippa is not guarded by Royal protection squad.
But there are concerns that an obsessed fan or terrorist could target her.
It is believed she already carries a police panic button.
A source told The Sun newspaper: “Pippa's car will have all the latest security devices, including armour plating. It will be bomb proof.”
