'Sk8er Boi' songstress Avril Lavigne has revealed that Nickelback rocker Chad Kroeger used a series of polaroid photographs to propose to her last year.

Speaking to Ryan Seacrest about her engagement, the star explained that he got really creative before popping the question and it surprised her: "The only thing that was weird was we usually go to the studio together and he had gone before me."

"And I have been making this scrapbook of my time in the studio with a Polaroid camera and the only thing that was weird was I walked into the studio and he was putting a picture in to the book and I was like 'What is he doing?'"

She added: "All of a sudden, I walk over and he had taken a photo of himself holding the ring box and put the Polaroid in my scrapbook and because I had stickers everywhere he put in, 'Will you marry me?' It was really romantic."

When asked about her upcoming wedding, Lavigne confessed that it will be a small ceremony but there is a big theme: "A lot of close friends and family (are coming); it's sort of smaller but it's going to be quite spectacular. There's a theme to it, we're going pretty big; but Chad doesn't even know everything yet!"
