Notice the date, though... June 12, 2014... TMZ broke the story in September of that same year and, within the article, you can see that TMZ said that Iggy claimed it was not her. Then, of course, it was revealed her jerk of a ex-boyfriend was behind it, she most likely wasn't aware of them being recorded, it died down completely, etc.
What connection does Sony have with "TI and Iggy Azalea"? Isn't she signed to Def Jam which is a part of Universal?!
