THIS is the moment Donald Trump crashed a wedding reception - delighting the bride and groom so much they led guests in a chant of “USA, USA”.

The US President, 73, was spending the weekend at his Bedminster golf resort in New Jersey when he walked into the bash for newlyweds Nicole Marie and PJ Mongelli.

Donald Trump beckoned the happy couple to come to him as guests quickly tried to film the arrival of the Republican leader.

Trump, wearing a dark suit without a tie, put his arms around the two as they took part in the “USA” chants, along with "Trump, Trump, Trump" while thrusting their arms in the air.

The President even kissed the bride and waved to the guests as they cheered him on.

Another video shows Trump being introduced to the couple.

“You’re a class act that you came in here,” the bride tells Trump.

The groom urges the president to stop in later for a couple of minutes.

“Please, please, it would mean so much to us,” he said.
