All stayed safely six-feet apart, practicing social distancing from their cars amid the COVID-19 pandemic.
Approximately 10-12 cars entered the couple's cul-de-sac with congratulatory signs and streamers and honked to surprise the couple.
"Oh my God!" a shocked Locken, 52, said in a video shared with PEOPLE of the surprise, as she and Emberlin exited their home to a sea of car horns. "Best surprise ever!"
"I just want to say thank you to everyone who showed so much love and kindness today," she later said on her Instagram Stories, according to PEOPLE. "It was felt and you made my one-year anniversary so special. And we both genuinely appreciate it."
