During a visit to a Royal Air Force (RAF) base in Cyprus, Prince William joked that his better half Kate Middleton was dressed like a Christmas tree.
As the royal couple posed for pictures with military personnel at RAF Akrotiri recently, William, 36, told Kate, 36, "My wife's camouflaged against the tree."
Before that, to give his wife a chance to pose by herself, the Duke of Cambridge humorously volunteered to step out of frame.
"Do you want me to move out of the photo?" he asked Kate, who wore a green blazer along with a navy wide-legged trousers for the visit.

The Duchess of Cambridge completed her look with a white silk top underneath, alongside a coordinating olive green clutch bag.
In addition to teasing Kate, William also talked about his son Prince George, who is a big fan of helicopters, while speaking to a group of pilots.
"I told George this morning we were going to see the pilots today, and he said, 'If you see a helicopter can you take a picture?'" William shared.
Meanwhile, according to reports, the royal family will celebrate early with two church services on Christmas day.
The Queen will take the communion during the first service, which is a private one for the family. It will take place at 9 am.
The entire royal family then return home to change their clothes before the public service at St. Mary Magdalene Church at 11 am.
George may go to his first service this year because royal tots usually join when they reach the age of five.
The little prince has been known for his cheekiness, and it turns out he's inherited a naughty habit that Princess Diana used to do at Christmas time.
With regards to celebrations, the Royals are known to adhere to the German tradition, as revealed by former royal chef Darren McGrady.
They usually open their gifts on Christmas Eve. However, little George has been spotted diving into his presents on Christmas day.
In a 2016 interview with KISS FM AJ King, Prince William revealed that the little prince was caught in the act unwrapping his gifts because he was so excited.
George inherited the habit from his late grandmother Diana who was also known for sneaking her gifts early.
The People's Princess once confessed about it in a letter she wrote to Janet Filderman, her beautician, on December 14, 1985.
