Lavigne finds lyrics Complicated

Canadian pop star Avril Lavigne has vowed to polish up on her lyrics before taking to the stage, after forgetting the words to her hit song Complicated during a show.

The 19-year-old singer was left so embarrassed by the incident, she now doubts she'll ever have any trouble remembering the lyrics again.

She recalls: "During one of my recent shows, I totally forgot the second verse of Complicated. I looked at Evan (my guitarist), and I said, right in the mic, 'I forgot the words.'

"Everyone started laughing. It was so weird."
