Iggy Azalea is hurling serious allegations against Universal Music Group. The rapper took to Twitter on March 15th, claiming the company owes her millions in unpaid royalties from international earnings.

It appears Drake isn’t the only recording artist that has an issue with UMG. Today (March 15), Iggy Azalea slammed Universal Music in a series of posts online (viewable here) claiming the company currently owes her millions in royalty back pay.

Iggy Azalea, real name Amethyst Amelia Kelly, claims that the company stiffed her on “millions of dollars in back pay,” and recently offered her an $18,000 settlement instead of the amount “in the 8 figure range” that she says she is owed.
