In 2011, he said he was proud Mac Miller's song -- that is named after him -- hit 20 million views on Youtube, but now, Donald Trump wants money for the use of his name.
The real estate magnate called out the 21-year-old rapper on Twitter (@realDonaldTrump), revealing that he was a plaque by Miller, but he could care less about it.
"Little @MacMiller sent me an expensive plaque for making his song 'Donald Trump' such a big hit. Mac, you still don't have the right to use my name," Trump tweeted, along with a photo of it.
"Donald Trump" originally appeared on Mac Miller's 2011 mixtape, Best Day Ever, and was released as a single on iTunes.
"Little @MacMiller, I want the money not the plaque you gave me!" Trump later added. "You illegally used my name for your song 'Donald Trump,' which now has over 75 million hits."
Trump continued, threatening legal action. "Little @MacMiller, I'm now going to teach you a big boy lesson about lawsuits and finance. You ungrateful dog!"
Then, came some taunts. "Little @MacMiller—I have more hair than you do and there's a slight age difference," the 66-year-old Trump said.
As of press time, Mac had not responded. However, in the past, he acknowledged that Trump was aware of the song.
"I was just excited that I reached the level where someone like that, I'm on their radar," Miller previously told Hardknock.TV. "He definitely thinks that he's the coolest man in hip-hop right now. He's like 20 million views... He's like, 'I'm pretty proud of that.' "
