Well, it seems Sia has a serious problem with Miz Lavigne because she recently revealed in an interview that she'd have no interest in writing for her.
"Avril Lavigne. Maybe she’s different now, but bratty people? No."
Avril has definitely got a reputation for being a little 'bratty,' so to say, but isn't that part of her punk princess identity??
Maybe Sia doesn't want to write for her because she doesn't think she's any good?!
Guess we'll never know what Sia + Avril would equal.
