Punk pixie Avril Lavigne wants to set the record straight: She didn't bad-mouth Britney Spears.

Lavigne was quoted in The Sun earlier this week saying, "What's happened to Britney is all down to who she is as a person." Only problem -- she didn't say it.

"I didn't say that," Avril told Los Angeles radio duo Valentine and Lisa Foxx this morning. "I haven't even been talking about her. People ask me about it all the time and I go, 'You know what? I don't know her.'"
