Nick Cannon, of 'Wild 'N Out' fame, performs at Roosevelt High School

Comedian and actor Nick Cannon electrified a high school pep rally on Long Island Friday, ahead of an upcoming event at Barclays Center later this month.

The celebrity is set to host a live version of his 21-season game show, "Wild 'N Out," on June 28 at the Brooklyn arena.

Students at Roosevelt High School cheered when Cannon ran onto the stage. They had been surprised by an appearance from Cannon's "Wild 'N Out" castmate Rip Micheals, who emceed the event.

Three student finalists participated in a rap battle, which focused on what happens "in the classroom," as the rap went. The students got creative when Cannon and Micheals kept the beat going and encouraged the student body to support.

Cannon ran through the auditorium to give high-fives to students, with school cheerleaders joining in on the fun.

Dalton Nembhard, 16, was in awe. "Once I saw 'Wild 'N Out,' I thought I would see Conceited or DC Young Fly, but I saw Nick Cannon," the 10th grader said, referring to two other prominent figures from the show. "I was happy to see that they would come all the way out to the high school. It shows the love that they have for us."

Roosevelt Principal Keith Saunders said the students needed and benefited from the energy and joy Cannon and Micheals brought to the rally. "The spirit of Roosevelt is electric right now. It was exciting for our scholars to have this experience right before the intense moment of regents exams," he said.

Cannon had also been set to visit Hempstead High School on Friday, but had to cancel as he was behind schedule, and will reschedule his appearance, according to Ron Edelson, a spokesman for the Hempstead and Roosevelt school districts.

The "Wild 'N Out Live: No Filter" event scheduled for later this month at Barclays will feature musical guests such as Soulja Boy and Bobby Shmurda, among other artists. The MTV comedy and improv series promises to bring a high-energy and interactive performance, with guest musical appearances.

Tickets to the show start at $30 for standard seating, reaching over $300 for front row, VIP packages.

Saunders said the event at Roosevelt was made memorable by the personal touches Cannon and his castmates brought to the school. "He took the time out to take photographs with each kid who wanted to take a photograph," Saunders said.

As the event came to a close, students followed Cannon as he exited the building, where he stuck around for a minute so students could snap a few more selfies with him and get autographs.

Correction: Nick Cannon rescheduled his visit to Hempstead High School, according to a spokesman for the district. An earlier version of this story was incorrect.
