While promoting her new album, This Is Acting, Sia sat down for a rather revealing interview with Rolling Stone—where she pretty much laid bare every fascinating piece of gossip the music industry has to offer.<br />Although the singer-songwriter has worked with every major recording artist there is, she had some pretty interesting things to say specifically about the unexpectedly flaky Rihanna and Kanye West.<br />On being stood up by Kanye West and Rihanna: "They'll entice me into a session by saying, 'Rihanna will definitely be there' or 'Kanye will definitely be there,' but it's hilarious because I turn up and, almost always, they never come.<br />So I went into the studio to write for Rihanna with Kanye and neither of them showed up and stayed for less than an hour.<br />They had two tracks.<br />They told me what they had wanted.<br />There were notes from Kanye, and I can't even remember what they were.<br />I remember I just raced in and raced out, and I thought there was something about the chorus that seemed fun about this song, but I never thought it would see the light of day.<br />My manager pushed for this song ['Reaper'] to be on the record, but I don't care about it."
