As his indictment looms, Donald Trump is still DJing at Mar-a-Lago, we hear.

The former president was at his Palm Beach, Fla., club Tuesday — the same day he had predicted he would be arrested — “surrounded by supporters, fist-pumping and giving the thumbs-up,” a spy told Page Six.

“He had a political dinner with five pals without Melania . . . The Donald was deep in serious conversation with what looked like political advisers.”

Meanwhile, the source said, “Trump couldn’t stop smiling as he played ‘Maria’ from ‘West Side Story,’ the theme from ‘Phantom of the Opera’ and a chorus of ‘Hallelujah’ that had people scratching their heads as to exactly what that meant.”

Page Six previously reported that Trump’s team is “pumped” about his potential arrest, thinking it will boost his re-election campaign in what’s predicted to be a run against Florida’s Gov. Ron DeSantis.

A source previously told Page Six of Trump and his supporters, “They are very pumped about this … The Manhattan DA, NYPD and even the Department of Justice were trying to work out a quiet handover coordinated with the Secret Service — and Trump was having none of that. If an indictment and arrest happens, he wants it to be public.”

We were even told that team Trump is planning to “try and film and document it with their own camera crew, they want a shot of him in cuffs and will release the mugshot. They are loving this stuff.”

The Post previously reported that sources said the NYPD and Secret Service are prepping for Trump’s potential indictment after the ex-president announced he expected to be arrested.

The possible arrest and indictment stem from Manhattan District Attorney Alvin Bragg’s probe into alleged hush money that was paid to porn star Stormy Daniels.

Daniels claims she had an affair with Trump in 2006, which he denies.
