It all started with Macklemore.

The Seattle rapper released a new song, "White Privilege II," in which he calls out Iggy Azalea, Miley Cyrus, and even himself for cultural appropriation. "The culture was never yours to make better," Macklemore raps.

When asked about the name drop, Iggy responded to a fan on Twitter, saying, "He shouldnt have spent the last 3 yrs having friendly convos and taking pictures together at events etc if those were his feelings"

Brooklyn hip-hop artist Talib Kweli took issue with her reaction, tweeting, "The fact @iggyazalea thinks Macklemore song was a diss to her, instead of actually listening, is proof of her privilege. F**k Iggy Azalea."

Respect for not subtweeting her and @ replying her in the message.

"True story. I actually rooted for Iggy when she first came out," Kweli continued. "But she's disrespected hip hop culture one too many times."

Iggy -- who is no stranger to Twitter feuds, having beefed with everyone from Snoop Dogg to Papa John’s Pizza -- obviously responded.

"I actually love hip-hop, I wouldn't endure the amount of shit I get if I didn't," the "Fancy" rapper tweeted back. "Maybe I don't showcase it in the way you like, but I do love it."

The 25-year-old singer then pointed out that she was marrying a black man, NBA player Nick Young, and, as she put it, "Will probably have bi-racial kids."

"I don't want them to be treated differently or have less opportunity for success because the system is not set up to benefit POC," Iggy tweeted.

And then it devolved into this:

"The world is FUNNY," Iggy concluded. "I'm not actually heated about Macklemore's song or its message. I don't think its intention was to make me a tending topic."
