Priscilla Presley has made a trip to Ontario this week, to take part in the annual Collingwood Elvis Festival.

This year marks the event’s 20th anniversary. It’s also the first time that Priscilla – once married the King of Rock and Roll — will participate.

“I don't even know what to expect I really don't so even though people tell me 'you're not going to believe it' I'm not, I'm sure I'm not, but I'm really excited about going,” she told CBC News in an interview.

It is the world's biggest tribute festival to Elvis.

This year the fest also comes with an exhibit of photographs from Priscilla Presley and Christopher Ameruoso — promoting their new book, Shades of Elvis
