The pop-punk singer released her latest CD Goodbye Lullaby last month and some fans believe the songs were written about her divorce from former husband Deryck Whibley.
"I wouldn't say it's a break-up record, it's about life," Lavigne told Rolling Stone. "I went into it with a mindset of not trying to write hits.
"People will make assumptions, but they'd be surprised what certain songs are about."
Avril recently revealed that Deryck is still her best friend despite their break-up. She also added that her brother and sister laughed at her singing before she became famous.
