India, Feb. 10 -- The royal couple, Prince William and Kate Middleton, have often been seen sharing a laugh together, and their witty exchanges don't just happen behind closed doors. According to one of William's advisers, Kate hadn't fully realised the importance of dressing carefully as a senior royal. On one occasion, this lack of awareness led to a brutal, yet funny, remark from her husband.

The adviser told The Times: "Before Kate realized that as a senior royal, you have to dress carefully, she once bought an outfit that William considered inappropriate. He told Kate she looked as if she'd just run through a charity shop covered in superglue. Everyone thought this was very funny, including, to her credit, Kate.

It's not just Willi...
