Brie Larson found herself part of a very special moment between two fans at a recent meet-and-greet.

53-year-old John Chambrone proposed to his boyfriend Richard Owen while meeting the Captain Marvel star at ACE Comic-Con in Illinois over the weekend.

John chose that moment to propose as the couple went on their first date together to see Captain Marvel (which must have been all of seven months ago but sure when you know, you know).

Needless to say, Brie was delighted.

John gave her a letter as he walked away to explain why he decided to "ambush" her with his proposal.
