Kate Middleton and Prince William put on a brave face and refused to allow the controversy over the publication of topless photos of the Duchess of Cambridge affect their royal duties. The royal couple are on a nine-day tour of the Asia-Pacific region to mark the Queen's Diamond Jubilee.

Kate and William are currently in Malaysia, on the second leg of their trip, and visited the Borneo rainforest in Sabah, east Malaysia, on 15 September. The royal couple left the Malaysian capital of Kuala Lumpur the previous day to travel to an area that is home to one of the few remaining stretches of primary tropical rainforest in South East Asia.

Catherine, the Duchess of Cambridge, who was reportedly furious over the invasion of her privacy and the release of the topless photographs, appeared calm and composed during the visit and looked as stunning as ever. According to royal aides, Kate was looking forward "immensely" to seeing this "virgin jungle".

The Duchess wore, appropriately enough, a jungle-themed outfit - a pair of cargo pants, brown boots and a matching leather belt with a midnight sky-coloured shirt. She completed the ensemble with a rugged brown bracelet and sported her natural hairdo - the glossy blow-dry style. The royal couple complemented each other... Prince William was also dressed in a cargo ensemble.

William and Kate walked through the rainforest to reach the Danum Valley Research Center, which is located deep inside the rainforest and is run by the Royal Society, of which the Duke is a Fellow. Their visit to the forest was planned because of William's longstanding interest in conservation, according to a Buckingham Palace statement.

"The visit is a means for The Duke and Duchess to experience the ecological wealth of Sabah's forests and the importance of supporting the efforts of the scientists working to understand and conserve them," the statement read.

The visit to the Royal Society marked the end of Their Royal Highnesses' visit to Malaysia, where the Duchess of Cambridge made her first official overseas speech.

The Duke and Duchess of Cambridge will conclude their Far East tour with visit to two Commonwealth nations, of which Her Majesty The Queen is Sovereign. These are in the South Pacific and the visits will be from 16 to 19 September. They will first travel to Honiara, in the Solomon Islands, followed by Tuvalu, to which they will travel by canoe.
