WATCH: Cobb teacher proposes to girlfriend at pep rally after lip-sync

Sydney Wright came to Lassiter High School on Friday to watch her boyfriend Robbie Galvin and a fellow teacher perform a lip-sync during a pep rally.

It was one heck of a performance — just ask her left hand.

After a brief rendition of the Backstreet Boys’ “I Want It That Way” Galvin’s buddy walks Wright to center stage on the gym mats in front of the students.

Then the song abruptly cuts off, giving way to a subtle use of Bruno Mars’ “Marry You.”

Galvin twirls Wright, and the hundreds of students start freaking out.

“I wanted to let you know that for most of my adult life,” he said into the microphone, “I’ve been praying for someone and I realized that that someone was you.”

Then the history teacher gets down on one knee and the place goes nuts.

Wright’s knees buckle as Galvin opens the ring box. She nods and they have some forehead-to-forehead time before she slips on the ring and they hug.

"Chapel of Love" — Goin' to the chapel and we're gonna get married... — starts playing and cheering from the students and both families continues.

"I think I was just shocked. It was so unexpected, like, so unbelievably unexpected," she told the Cobb schools communications staff afterward. "I kept waiting for something else to happen, nothing else was happening and then he just kept going with it and I was like 'Oh my gosh, this is happening.'"

Galvin, also a coach of the girls varsity soccer team, wanted to have the Lassiter community be a part of their special moment.

“Lassiter is a huge part of my life … Sydney has embraced that, and we feel like we’re going to share a life together, and this is something she loves as well, so I figured proposing at a pep rally would be really special for both of us as well as special for all of these kids here at Lassiter who mean so much to me,” he said.

At the time of publication, it wasn’t immediatley clear if the Lassiter Trojan mascot would officiate the wedding.
