(Cover) - EN Showbiz - Journalists have reportedly "been sternly warned" not to ask questions about Prince Harry's photo scandal.

The British royal has been making headlines after photos emerged showing him partying stark naked in a Las Vegas hotel.

The Duke and Duchess of Cambridge are preparing to travel to the South Pacific to tour Singapore, Kuala Lumpur, the Solomon Islands, Borneo and Tuvalu.

Royal journalists accompanying the couple must not discuss Prince Harry's wild Vegas night.

"Journalists who are travelling on William and Kate's trip have been sternly warned that questions about Prince Harry are out of the equation," a source told Radar Online.

"This is a royal engagement, a nine-day trip that has been organised by the Queen for her grandson and his wife, who are keen to pay tribute to her life of dedication and service.

"It holds specific importance because Singapore and Kuala Lumpur are Commonwealth countries and William and Kate's visit will strengthen diplomatic and trade links in the region.

"So, because of its importance, the Palace has said that anyone that quizzes William and Kate about Harry's naked escapades in Las Vegas will be sent home. He's a topic that is off limits." (C) Cover Media
