Sandor Sturbl stunned the audience and his girlfriend as he popped the question to his Scottish co-star Lilly-Jane Young as they performed at the Hydro in Glasgow.
The Dutch romantic got down on one new near the end of the new musical, stirring cheers from the audience and co-stars as he told them "this is not a normal show this evening".
The pair had been dating for just over a year and 22-year-old Young told the Daily Record she was shocked but stoked with the gesture.
Watch the proposal:
"I thought it was a technical hitch and was staring to panic when Sandor turned to the audience and said, 'Well, ladies and gentlemen, this is usually the moment when Peter Pan gives Wendy a kiss. Lilly-Jane is the love of my life.
"She's from Glasgow and performing here means the world to her. That's why I want to ask her to marry me.'
"I couldn't believe it. I said, 'Yes' straight away and all of the audience started clapping.
"It was a magical moment and one I'll never forget."
