And so it was for Avril Lavigne as she left her stroppy teenage image behind and opted for a stunning Vera Wang dress for her weekend wedding.

The 21-year-old skater chick - who's recently dabbled in Hollywood movies - has become the wife of Sum 41 singer Deryck Whibley.

The Canadian singer said 'I do' in front of 110 guests at an outside ceremony at a luxurious estate in Montecito, California.

The original date for the big day was for some time in August, but members of the young couple's families and friends were informed of the new plans just days ago to avoid the media hype.
