FORT WASHINGTON, Pa., Nov. 12 (UPI) -- Film star Bradley Cooper wore jeans, boots and a Philadelphia Eagles hat to his 20-year high-school reunion in Fort Washington, Pa., E! News reported Tuesday.

Members of Germantown Academy's class of 1993 recently met at MaGerk's Pub & Grill.

"It was a small, private event," a source told E! News. "There were about 30 to 45 people."

The "American Hustle" and "Silver Linings Playbook" actor arrived without security to the event.

"He was very casual," the insider said.

"A super nice guy and seemed happy to be there," the source said, adding, "He took some photos with classmates," who "were just treating him as one of their classmates."
