A 'furious' Duke and Duchess of Cambridge have been forced to put a brave face on a distressing situation yesterday after a magazine published pictures of Kate topless.The royal couple is considering legal action against Closer in France, but had to put that to one side as they attended a tea party held in their honour in Kuala Lumpur.A spokesman for the couple told Mail Online today: 'Their sadness has turned to anger and disbelief as we have learnt more about the photographs. We believe a red line has been crossed and we are consulting the French lawyers to see what, if any, action can be taken.But in a show of unbelievable strength the Duchess of Cambridge managed to smile and laugh her way through a Diamond Jubilee tea party at the British High Commission. Kate sipped tea and chatted to several guests including shoe designer Jimmy Choo.She appeared determined not to let the strain of the morning’s revelations show - laughing and chatting to the designer without an apparent care in the world – although William at times did appear to have the weight of the world on his shoulders. The couple was informed over breakfast of the scandal shortly before they departed to visit a mosque in Kuala Lumpur and have seen copies of the pixellated photographs.Sources said the Duchess and her husband were 'hurt, shocked, furious and disgusted'.The anger had not subsided for Prince William as they then left the capital of Malaysia for the next leg of their tour of south east Asia. Trailed by their closest aides and airport staff, the couple walked the 200 yard red carpet laid out at the Bunga Raya VIP area of Kuala Lumpur's airport today.
