The singer's fourth studio album Goodbye Lullaby faced a number of delays after RCA bosses told her that they wanted a more commercial sound, but Lavigne stood her ground and has now revealed that she is proud of the finished product.
She told the News of the World: "It's hurtful actually. I put so much into this record, but the record company were kind of cold. But what it came down to was they really wanted me to go in a different direction and that was not OK with me.
"I've been doing this for ten years now and I write my own music. All of these new people were telling me what to do and I was like: 'NO, NO, NO!' This is my fourth record and I'm 26 so it's time for me to do something a little different. I love this record and I'm really proud of it."
Speaking of working on the record with her ex-husband - Sum 41 frontman Deryck Whibley - she added: "He's my best friend, we are still really close. I was so lucky to have him be a part of this record. He is one of the most talented people I've ever worked with."
Goodbye Lullaby is released tomorrow in the UK.
