“They were dressed with what they had on at the Grammys,” One Love Wedding Chapel owner Marty Friersontold PEOPLE. “They came, got married, tossed the bouquet in the driveway, and danced to Elvis. It was over in about 30 minutes.”

“There was a lot of that — kissing and hugging. They barely came up for air!” he says. “They just seemed totally in love.”

“They all had iPhones, taking pictures and videos from every angle,” he added. “I don’t know if they were the friends or their social media team. They filmed everything from the time they walked in, to the time they walked out. The vows, the kiss, the rose bouquet toss, the dancing. I usually take pictures for the chapel but they wanted to handle it all themselves.”

At the time, a source told PEOPLE the proposal location is one of the couple’s “favorite” spots
