The nutjob accused of repeatedly stalking Donald Trump’s daughter Ivanka claimed yesterday he’s being controlled by space aliens.

The outburst by Justin Massler, 28, helped convince a judge yesterday that he’s unfit to stand trial — at least for now.

Manhattan Supreme Court Justice Lewis Stone sent Massler to Bellevue Hospital.

Massler told his lawyer George Vomvolakis — in comments clearly audible to spectators — that extraterrestrials were messing with his head.

“Well, what it is, is the psychiatric system is corrupt,” Massler said. “I’m under supernatural influence. Aliens could have been involved.”

Stone ruled that Massler should be brought back to court in a year, unless shrinks find that he’s fit for trial before then.

Even though he has a lawyer, Massler insisted on speaking for himself. He asked the judge: “Am I not allowed to make a statement?”

The judge urged Massler to do all his talking through this lawyer.

“Well, you’re unfit for trial. I really can’t speak to you,” Stone told Massler.

When Stone made his ruling, the Reno, Nev., resident couldn’t believe it.

“So I’m going to the psych ward?” Massler said.

The judge nodded and a disappointed Massler replied: “Oh, man!”
