Chi Shifts Attention to Pippa Middleton: Duchess of Cambridge's Sister Pictured with Mystery Man

Italian magazine Chi is once again the centre of controversy. The publication fell afoul of the royal family last year when they were one of several publications to print topless photographs of Kate Middleton, taken while the Duchess of Cambridge and Prince William were on a private holiday in the south of France.

More recently, Chi published photographs of a pregnant Kate Middleton, wearing a blue bikini, on holiday in the Caribbean island of Mustique. The 31-year-old Duchess was in the Caribbean with Prince William and her family (Michael and Carole Middleton and siblings Pippa and James). Kate and William are expecting their first child in July.

Chi has now published more photographs of the Middleton's holiday in the sun. This time, it is Kate's younger sister, Pippa Middleton, who is the centre of attention. The 29-year-old was photographed, in an orange and pink bikini, holding hands with an unidentified brown-haired man. The magazine claimed the man was James Matthews, chief executive of the Eden Rock Capital Management Group. However, sources close to Matthews have denied the report.

Chi has already come under fire for publishing private photographs of the royal couple's holiday but the magazine's editor, Alfonso Signorini, said the reaction from St James' Palace reaction was over the top and that the photographs were taken in a public place.

The Duchess, who is on a brief break from her royal duties, will make a public appearance on 19 February, when she visits a rehab centre in south London. The visit will be for the charity organisation, Action on Addiction.
