Iggy Azalea slammed Britney Spears on Twitter admits their ongoing social media feud over the unsuccessful trajectory of their "Pretty Girls" song. 

"Genuine friends have genuine opinions. Its possible & healthy to have a differing thought without it being bitchy or shade," she posted on Twitter. 

"Can't wait to get back to Vegas. So thankful I have shows for the rest of the year to look forward to... #YouWantAPieceOfMe," Britney Spears posted shortly after. 

Iggy Azalea recently posted a message on Twitter that sparked rumors suggesting that she is depressed. 

"Its really tough to stick by someone when the 'cool' thing is to hate on them," she posted. 

"Thanks to everyone who made the choice to stand by me."

The "Fancy" singer announced via Twitter that she would no longer perform in Pittsburg because of controversy over racist and homophobic comments she made several years back. 

"I am a firm believer in equality. Unfortunately in the past as a young person, I used words I should not have," she wrote. 

"The last thing I want is for something so carelessly said to be interpreted as reflective of my character. ... I meant no harm and deeply regret ever uttering those words."
