Temperatures ran high at a Staten Island wedding over the weekend because Guardian Angels founder Curtis Sliwa and John Gotti Jr. were both guests — which was awkward, since Gotti Jr. was charged with the kidnapping and attempted murder of Sliwa back in the ’90s.

We’re told that the pair were kept “on opposite sides of the room” at the nuptials of AM 970 host Frank Morano at the Hilton Garden Inn.

Sliwa — who founded the amateur crime-fighting group in 1979 — was kidnapped in a stolen taxi in 1992 and shot multiple times by a gunman who had been hiding in the front seat.

Sliwa had made disparaging remarks about Junior’s father, John Gotti, the late boss of the Gambino crime family. Gotti Jr. was tried multiple times, but never convicted.

After the wedding, Sliwa told us that he struggled to keep his mind off his fellow reveler.

“I would look in [Gotti Jr.’s] direction … You couldn’t miss John and his sister [Victoria Gotti].”

“To use street terminology, I was mad-dogging him,” he said, meaning that he was staring daggers at Junior. He added, “People were reminding me this was my friend’s wedding — don’t make a scene; don’t get into a dust-up.”

“There were a lot of people … taking my temperature and trying to distract me,” he said.

Also at the celebration was Maureen Gioeli, the wife of Tommy “Shots” Gioeli, an alleged high-ranking member of the Colombo crime family, and lawyer-turned-felon Frank Gangemi.

Former New York Lt. Gov. Betsy McCaughey, Assembly member Nicole Malliotakis, Staten Island Borough President James Oddo, City Council Minority Whip Joe Borelli, former Rep. Dan Donovan, billionaire John Catsimatidis and Harvey Weinstein lawyer Arthur Aidala also attended.

Former “SNL” star Joe Piscopo, who brought model Carol Alt, sang “New York, New York” and “That’s Life.”
