Russell Brand and Katy Perry's Wedding to Be Clothing Optional

02/01/2010 AT 10:25 AM EST

Russell Brand has absolutely no secrets to divulge about his upcoming wedding to Katy Perry. Well, maybe he can share a minor detail about the dress code.

"We are going to do the wedding naked! All the families will be naked!" Brand joked to PEOPLE at Sunday's 2010 Grammy Awards.

He's kidding. "We're still deciding what to do," he says. "There's no juicy details yet."

But actually, a naked ceremony is one of the less quirky visions Brand has had for the wedding day.

"All my dream weddings don't make sense," he says. That's probably because his dreams – the literal, nighttime kind – can be a bit hallucinatory.

"The vicar will start melting," he says. "The people in the front row will turn into people from my school. And then everyone will only say the word 'potato.' "

But in all seriousness, Brand, 34 – who recently threw an engagement party in Beverly Hills with his fiancée, 25 – says life is firing on all cylinders.

"I'm getting married to a beautiful woman," he says. "I'm enjoying my work."

What could be better? "Nothing," he says."
