Avril Lavigne says her upcoming wedding is going to be ''quite spectacular''.
The 28-year-old Canadian star - who was previously married to Sum 41 frontman Deryck Whibley - has admitted she is planning a very lavish big day with her Nickleback rocker fiance Chad Kroeger and plans to surprise him with a few romantic details.
In a joint interview with Chad on Tuesday (09.04.13), the 'What The Hell' singer told KIIS-FM's On-Air with Ryan Seacrest: ''It's going to be quite spectacular, and there's a theme to it.
''We're going pretty big, but Chad doesn't even know everything.
''I'm going to take the lyrics from the sheet music from one of our songs and wrap it around the wedding cake.''
Avril also opened up about how Chad, 37, proposed to her with a 14-carat diamond ring last August, after just one month of dating.
She said: ''I had been making this scrapbook of my time in the studio. I walk over and he had taken a photo of himself holding the ring box and put the Polaroid in my scrapbook. Because I had stickers everywhere he put in 'Will you marry me?' It was really romantic and kind of made sense.''
Chad revealed he was very nervous beforehand.
He explained: ''You can travel the world and sing songs to thousands of people and not have your heartbeat raised at all. You get down on one knee and commit yourself to a woman for the rest of your life. I was very nervous!''
The singer previously admitted he never expected to get married but meeting Avril changed his mind.
He added: ''There was a time in my life that I thought I would never get married. But this definitely took me by storm. Honestly, it was more my idea than hers to get married. I'm just lucky she said yes.''
