Avril Lavigne has spoken about her romance to Nickelback's Chad Kroeger, reiterating that it developed as they worked on music together.

The Canadian couple turned heads last year when they revealed that they were engaged together - an announcement that largely came out of the blue.

Speaking to Hello! UK, Lavigne said that their love was ignited when they were creating music together for her new album. She said:

"It evolved into this wonderful thing. When you're sitting there singing across from somebody into the microphone and you're singing a love song, you start to develop these feelings for that person, and it just blossomed into this thing."

Speaking about their wedding, the 'Sk8er Boi' star added: "Some things will be a surprise. Some things will be what he likes and still will surprise him! Our wedding song will be a duet we recorded together for my new album."

Lavigne meanwhile won a gong at the MuchMusic Video Awards on Sunday night (June 16) for her 'Here's To Never Growing Up' promo.
