Donald Trump has threatened legal action against Mac Miller over his gold-certified song “Donald Trump.”

The Donald Trump / Mac Miller feud continued on Twitter earlier today as Trump blasted the Pittsburgh, Pennsylvania rapper, defying earlier statements that he was “proud of him” and that he is the “new Eminem.”

“Little @macmiller, you illegally used my name for your song ‘Donald Trump’ which now has over 75 million hits,” he wrote. “Little @macmiller, I want the money not the plaque you gave me! Little @macmiller, I’m now going to teach you a big boy lesson about lawsuits and finance. You ungrateful dog! Little @macmiller—I have more hair than you do and there’s a slight age difference.”

Trump, known for his Twitter antics, previously praised Mac for the song back in August 2011. “A lot of people are calling me about the Mac Miller rap song. Now, it’s named ‘Donald Trump.’ Maybe you should pay me a lot of money, but it just did over 20 million people, tuning into Mac Miller,” he said. “So in one way, I’m proud of him. I haven’t actually seen the language, it’s a little hard to understand on the song itself. Probably, it’s not the cleanest language you’ve ever heard, but this kid is the new Eminem. Everybody says he’s fantastic. Let’s see what it is. But the ‘Donald Trump’ song just hit over 20 million, that’s not so bad. I’m very proud of him.”

Miller later responded, “I was just excited that I’ve reached a level where someone like that, I’m on their radar. I’m ‘bout to hit him to borrow the jet real quick.”

The rapper is yet to speak on the matter. He recently settled a $10 million lawsuit from Lord Finesse over copyright infringement.
