VIDEO : Taylor Swift And Justin Bieber Fight After Her Music Catalog Snafu

Pop superstar Taylor Swift has attacked Justin Bieber?s manager for buying her music catalog.
This prompted Bieber to come to his defense in a heated online spat, reports Reuters.
Swift on Sunday wrote a lengthy post on Tumblr voicing dismay that Scooter Braun was acquiring Big Machine.
Big Machine is a Nashville-based record company that owns the master recordings of her past songs.
A rep for Braun, who owns the company Ithaca Holdings, did not respond to a request for comment.
Ithaca Holdings LLC acquired the Big Machine Label Group but terms of the deal were not disclosed.
Halsey and Cher expressed support for Swift in online posts, while Lovato came to Braun?s defense.
