Trump, Dana White's star-studded White House UFC event draws big names while several invited A-listers skip

From athletes and influencers to political allies and celebrities, President Donald Trump's highly anticipated White House UFC event drew a host of high-profile guests. Still, despite the star-studded crowd, several A-list celebrities reportedly invited to the event were notably absent.

Trump marked his 80th birthday Sunday night with a celebration on the South Lawn, where 14 fighters from around the world competed inside a wire-mesh cage during the UFC Freedom 250 spectacle.

The estimated 4,300 people in attendance, which included about 1,200 active-duty service members, greeted the president with loud cheers as the occasional "Happy Birthday" was shouted from the crowd. 

The $60 million event kicked off with the Marine Band’s performance of the national anthem, sung by country star Zac Brown, and was capped off with a flyover by the Navy’s Blue Angels and Air Force Thunderbirds.

In May, UFC President and CEO, Dana White, confirmed to Time magazine that he had extended invitations to major celebrities such as Adam Sandler, Guy Ritchie, Tom Brady, Jared Leto, Jason Statham, Dwayne "The Rock" Johnson and Mario Lopez.

"Man, I’m there for the troops, man. I’m there to honor America, this is patriotism, not politics for me," Brown said. "I mean, screw every division. I don't believe in that. Adore this nation. I adore everyone who has made sacrifices to enable me to live the American dream, and I believe that everyone in this country has the opportunity to do so if they put in the necessary effort and make wise choices. Therefore, I don't think it belongs in politics."

Many of the fighters thanked Trump for having the "courage" to put on the spectacle, while the majority of victors jogged ringside to shake his hand or have a word after their respective bouts. The patriotic atmosphere set the tone for the remaining America 250 celebrations to come in Washington, D.C., later this summer.

"It was beyond anything that anybody's ever seen in sports," the president briefly remarked to reporters as he departed the White House ahead of Monday’s G7 summit in France.
