Prince William's RAF friends played the funniest pre-wedding prank on him

Prince William's military friends once played a hilarious prank on the royal in the lead up to his wedding day.

• Prince William's RAF colleagues played a hilarious prank on the royal in the lead up to his wedding
• The Duke of Cambridge left the armed forces in 2013 after a seven-year military career
• In other royal news, the Queen has the final say on this major element of all royal weddings

The prince served in the Royal Air Force for four years between 2009 and 2013, when his military career ended. His fellow servicemen clearly treated him as one of their own as they played some tricks on him ahead of his wedding to Duchess Catherine. 

The Duke and Duchess of Cambridge will celebrate their 10 year anniversary this year, having tied the knot at Westminster Abbey, London on April 29th 2011. We can't believe it was that long ago either – time flies!

The couple have since gone on to start a family and now have three children together – George, seven, Charlotte, five, and Louis, two.

But back to the royal wedding and that prank. HELLO! reports that ahead of the big day 10 years ago, the prince's RAF friends dotted various commemorative souvenirs featuring William and Catherine all over their military base.

"We spent a few pounds on Kate and William memorabilia and strategically secreted it around the place," one of his colleagues revealed.

"So he might find his own face on a cushion or see it on a cup when you give him a cup of tea." 

Hilarious!
