Sir Paul McCartney is going political on his next album.

The Liverpool Echo reports the Beatles legend told students at the Liverpool Institute of Performing Arts last week that he's written a new song about President Donald Trump. He did not say what the track will be called or when it will be released, but hinted it won't be a favorable look at the U.S. president.

"Sometimes the situation in the world is so crazy, that you've got to address it," McCartney told LIPA students, according to the publication.

Billboard reports McCartney is a co-founder of LIPA and was a student there when it was known as Liverpool Institute High School For Boys.

The 75-year-old singer-songwriter told Australia's Daily Telegraph earlier this month that he's "not a fan" of Trump.

"He's unleashed a kind of violent prejudice that is sometimes latent among people," McCartney said. "He's unleashed the ugly side of America. People feel like they have got a free pass to be, if not violent, at least antagonistic towards people of a different color or a different race. I think we all thought we'd got past that a long time ago."

McCartney showed his support for Democratic presidential candidate Hillary Clinton during the 2016 election by posing for a photo with her in Cleveland. "She's with me," he wrote on Twitter.

Trump reportedly spoke out about McCartney in the past. In 2006, he told Larry King on CNN that the musician should've gotten a prenuptial agreement before marrying Heather Mills, who he divorced after six years of marriage.

"He insisted on no prenup and it's going to cost him a lot of money. And, I told him... Prenups are very tough," Trump said. "So, there's nothing really nice about it but in our world with the long courts and with the vicious lawyers and with all of the problems if you have money or if you think you're going to have money, you have to have a prenuptial agreement."

McCartney is expected to release his next album, currently untitled, later this year. He recently collaborated with Beatles bandmate Ringo Starr, Edgar Winter, Joe Walsh and Toto's Steve Lukather on a new song "We're on the Road Again."

The two-time Rock and Roll Hall of Famer will perform in Syracuse for the first time on Saturday, Sept. 23 at the Carrier Dome. Tickets sold out quickly.
