In case you have been leaving under a rock Demi Lovato, Justin Bieber and Ariana Grande's manager Scooter Braun bought out Taylor's old label Big Machine Records which in turn means he can now profit off every single album Swift has released thus far.
Like anyone, the 29-year-old singer took to social media to release a lengthy open letter slamming the music manager for his bully tactics and his involvement in the entire Kanye West and Kim Kardashian drama.
Bieber then later came out in defence of Scooter and slammed Taylor for making her gripe public.
"What were you trying to accomplish by posting that blog? seems to me like it was to get sympathy u also knew that in posting that your fans would go and bully scooter" he wrote.
Since then there has been an all-out celeb war on social media with many of Swifties allies jumping to defend her, including Halsey, Todrick Hall and supermodel friend Cara Delevingne.
