Lavigne revealed that she will have a "heavier song" with Marilyn Manson titled "Bad Girl," as well as a duet with Kroeger. She'll also have a tune called "Hello Kitty," about her love for the Sanrio character, which Kroeger describes as "aggressive." She'll be singing in Japanese, adding, "I love Hello Kitty so much there's a song on the record called 'Hello Kitty.' Pink is my favorite color... I'm really excited about this song. I'm obsessed with Hello Kitty and it's really fun and the sound is different."
The album will have "a lot of power ballads, piano ballads, string arrangements," she said, but it is mostly unfinished.
