June 11 (UPI) -- Ultimate Fighting Championship events planned for this weekend on the White House lawn are costing more than $60 million, a court filing said.

The price includes food, the "octagon" cage and 494 port-a-potties on the South Lawn, CNN reported. The event is happening Sunday in celebration of President Donald Trump's 80th birthday, Flag Day and ahead of the country's 250th birthday on July 4.

"In preparation, well over $60 million and tens of thousands of hours of labor have been expended. More than 4,000 spectators are expected to attend on the South Lawn, including more than 1,000 members of our armed services, and more than 120,000 visitors are expected to watch from the nearby Ellipse after winning free tickets in a lottery," a Tuesday filing from the government said.

The event will be held at the South Lawn, while the Fan Fest and ceremonial weigh-in will be at the Ellipse. Court documents say that about 125,000 people are expected to attend and another 75,000 requested tickets.
