So much stuff happens behind the scenes.
For example, Sia tweeted about having migraines while doing some work/promo or whatever out in Vancouver, Canada. Shortly after that, Sia tweets about receiving a bouquet of flowers and a hand written Get Well note from Christina.
She flew out Ladytron (from the UK) back in late 2008 and let them stay at her home while they worked on the album off on over an 8 month period. RCA cut out most of their work from Bionic which still PISSES ME OFF until this day. At least there is some hope Ladytron might make it on the new album because they recently said they were submitting demos to Christina. *crosses fingers*
There is SO much more details that went on behind the scenes regarding Bionic. SO MESSY.
