Ugh I'm so sick of this story and I feel like it's everywhere. I've heard it so many times. Are there seriously people in the GP who still don't know Sia wrote Diamonds and Pretty Hurts? And that PH was originally for Katy Perry who didn't see the email, so Rihanna put it on hold but didn't put the deposit down, so Beyonce and her team scooped it up, so Sia felt bad and offered Rihanna Diamonds, which went on to become a MASSIVE #1 hit.
I love Sia but every time I hear this story I'm like "yes, we know, the whole world knows, omfg"
