Rudy Giuliani's 80th birthday bash was a who's who of MAGA world. 

Republican provocateur Roger Stone and former Trump strategist Steve Bannon were among the 200 guests who turned out for the party in Palm Beach, Florida, where the guest of honor belted out a version of 'New York, New York,' with a Frank Sinatra cover band.

But the evening turned sour as Giuliani left the party just after 11pm.

Two officials with Arizona attorney general's office served notice of his indictment in the Arizona 'fake electors' case, accusing him and other's of trying to overturn the 2020 election result in the case. 

'The mayor was completely unfazed and even laughed as he was handed the papers and drove away,' said an outraged attendee.

'Guests were visibly angry as they shouted at the individuals that served the former mayor.'

Some were left in tears, said the source, as if it were all a part of an effort to humiliate and intimidate Giuliani and his friends. 

Earlier Giuliani taunted Arizona officials from the party, posting on X that they were running out of time to serve him in the case.

Prosecutors had been trying for weeks to deliver official notice that we he has to appear in court on May 21.

Arizona Attorney General Kris Mayes declared victory at around 11:20pm. 

'The final defendant was served moments ago,' she wrote on X. '@RudyGiuliani nobody is above the law.'

It came after guests had mingled on the terrace, and watched Giuliani record an hour-long episode of his 'America's Mayor Live' show.

They sang 'Happy Birthday' and presented Giuliani with a red, white and blue frosted cake. 

'It was a wonderful evening celebrating an America hero, Rudy Giuliani,' said Caroline Wren, a top GOP consultant who hosted the birthday party at her home in Palm Beach.

'It's a shame that while the Arizona southern border is wide open and crime is reaching an all time high, the Arizona secretary of state's office thought it was a good use of resources to send agents across the country to serve an indictment to a man who was celebrating his 80th birthday amongst friends and family and has spent his entire life dedicated to law and order. 

'This is what the Left does to people they fear. 

'They fear Rudy Giuliani because he’s one of the greatest prosecutors in American history and one of the strongest voices in the America First movement - so of course they must try to silence, indict and humiliate him - but luckily the American people can see right through this outrageous lawfare.'

Giuliani spokesman Ted Goodman said the former New York mayor was unfazed by the episode.

'He enjoyed an incredible evening with hundreds of people who love him – from all walks of life – and we look forward to vindication soon,' he said.

Giuliani came to global prominence as the mayor of New York City on 9/11. In recent years he became known as Donald Trump's personal lawyer, and a key adviser on his efforts to hold on to power after the 2020 election.

Several members of Trump's inner circle have been indicted in the Arizona case.

The include his former White House Chief of Staff Mark Meadows, legal adviser Boris Epshteyn, and former campaign aide Mike Roman. 

Trump himself is not named in the indictment, but he is believed to be 'Unindicted Coconspirator 1.'  

'In Arizona, and the United States, the people elected Joseph Biden as President on November 3, 2020,' the indictment reads. 

'Unwilling to accept this fact, defendants and unindicted coconspirators schemed to prevent the lawful transfer of the presidency to keep Unindicted Coconspirator 1 in office against the will of Arizona’s voters.'
