Mac Miller and Donald Trump have been known to go at it on Twitter in the past, ever since Mac's viral hit "Donald Trump" dropped. The two have had a complicated relationship, first it seemed Donald was on board with Mac's single named after him, but soon after he changed his tune, saying he would sue Mac Miller over it.

Now Donald Trump has once more taken an unprovoked shot at the Pittsburgh native. Mac Miller is dropping his new album, Watching Movies With The Sound Off, on June 18th, and it seems like Donald caught wind of this, and is hoping Mac will bomb.

The mogul tweeted, "Little Mac Miller’s next album may bomb. He can’t use my name again for sales."

You can judge for yourself, as album snippets for Mac's LP were released today. Listen here.
