JAY-Z and Kanye are sharing the throne again.

But Hov isn't about to let bygones be bygones.

While JAY is going to be on Kanye's new album Donda, he takes aim at Kanye's MAGA stance on the project.

"Stop all of that red cap, we going home," Jay-Z raps, according to the Los Angeles Times.

The LA Times report is from a couple of weeks ago, so it's possible Ye -- who's albums are always evolving -- has nixed those bars.

Donda might drop next week.  Or it might not.
