WATCH: Virginia cop dances to Beyonce's 'Formation' at pep rally

STAFFORD, Va. -- A high school pep rally in Virginia was taken to a whole new level - thanks to a police lieutenant who showed off his dance moves to Beyonce's "Formation."

Lt. Deuntay Diggs said he was asked to dance with the students at North Stafford High School, where his fiancee teaches, at their Oct. 14 pep rally, after a video had gone viral of him dancing to "Formation" at a police charity event.

Diggs is also a motivational speaker known in his community for tackling issues of race, sexuality and diversity.

While he didn't plan on performing Beyonce again, Diggs said there was a lull during the high school event, which gave him the opportunity to surprise the teens, who screamed in excitement.

A teacher shot the video and posted it on social media. The dance ended when Diggs dropped down in a split and students couldn't contain themselves. They ran out onto the court cheering.

"Being called a celebrity was never really the goal," Diggs told ABC News. "I feel like I'm just a regular person trying to do some positive in the community and help inspire others to go in the right path. In my mind, I'm having fun with the kids and the faculty and I never thought it would take off like this."

Diggs said the love he received from the kids couldn't have come at a better time, since he had received news of his mother's terminal cancer just days before.

"Dealing with my mom, I was feeling down and being with the kids in the gym in was an amazing moment," he said.
