Prince William and Prince Harry's unusual on-set nickname revealed

Prince William and Prince Harry are usually addressed as 'Your Royal Highnesses' during official engagements, but the brothers were given an unusual joint nickname – 'Sausage' – during their visit to the set of BBC network home improvement show DIY SOS in September.

The show's host Nick Knowles told HELLO! that the down-to-earth brothers asked to be called by their first names during their day on the site. "I'd been told I should address them as Your Royal Highnesses, which I did as I welcomed them," Nick recalled. "Then I said: 'How should we do it from here?' and they told me: 'Just Wills and Harry will do.'"

But one member of the team broke protocol by addressing them with another name entirely. "Billy, our electrician, calls everyone on site 'Sausage', so he tried: 'Your Royal Sausage'," Nick revealed. "Harry said to him: 'Listen, if you're going to call me Sausage, it's going to be a very long day!'"

In their own version of Property Brothers, William and Harry joined forces to turn derelict houses in Manchester into homes for ex-service personnel on September 23. They joined the DIY SOS team for the final stages of The Big Build: Veteran's Special project, which renovates eight buildings, streetscape an entire street and rejuvenate the façades of 62 houses.

During the visit the Princes helped put the finishing touches to the houses alongside ex-servicemen and women, who are developing skills in a new trade.

Both William and Harry have been busy in the public eye lately, including joining Kate Middleton at the Rugby World Cup. Prince Harry, who recently returned from a three-month trip to Africa, was spotted at the rugby competition with Kate's mom and dad, and this week also made quite a funny impression at the WellChild Awards in London.
