Sia hates artists who take credit for writing lyrics when they had nothing to do with it at all. She's already said that Rihanna and Ke$ha aren't lyric thiefs...but who could she be referring to? She said she wants to write for Kelly, Britney, Lady GaGa, and Nicki. The only person she didn't answer any tweets of was...Beyonce.
I mean, the only big named person I could think of is Bee. She said it wasn't Rihanna or Kesha, and if it was Christina, she probably wouldn't have worked with her a 2nd time. Who else has she worked with recently?
