Russell Brand has joked that he wants to marry fiancé Katy Perry in a "naked" wedding service.

He told People: "We are going to do the wedding naked! All the families will be naked! We're still deciding what to do. There's no juicy details yet."

The 34-year-old went on to say that his nerves ahead of the big day are starting to manifest themselves as he sleeps.

He explained: "All my dream weddings don't make sense. The vicar will start melting. The people in the front row will turn into people from my school. And then everyone will only say the word 'potato'."

Brand added that he can't wait to walk down the aisle, saying: "I'm getting married to a beautiful woman. I'm enjoying my work. What could be better? Nothing!"
