Jess Seldon, 27, had been told Alex would pass by to give her a high five. Instead, Alex picked up a ring from his best friend waiting nearby before making his way over to her.
"She was completely surprised, I don't think she knew what I was doing," Alex said.
"I tried to get down on one knee, to be traditional, but it was obviously pretty difficult.
"It was fantastic, almost surreal - so much so that I had to text her at the end and ask if she meant to say 'yes'."
