The three men will appear together at a fundraiser for Romney's presidential bid at Trump Towers on May 29, NBC News reported on Thursday.

In February, Romney received Trump's endorsement during a press conference at the casino. The former Massachusetts governor went on to a commanding win in the state's caucuses, which Trump took partial credit for. Gingrich endorsed Romney shortly after he ended his own presidential bid.

Romney's campaign is also fundraising off a chance to dine with Trump, along with Romney, in New York City. Any supporter who makes a donation will be entered in a raffle to win a trip and dinner with the two men.

The invite reads "I want you. Dine with The Donald and Mitt."

The winner receives: "Airport transportation in the Trump vehicle. Stay at the Trump International Hotel & Tower New York. Tour The Celebrity Apprentice Boardroom. Dine with Donald Trump and Mitt Romney."

President Obama used a celebrity fundraising pitch from George Clooney to raise $15 million for his presidential bid. Obama is now offering donors a chance to dine with him, actress Sarah Jessica Parker and former President Clinton.
