Superheroes to the Rescue! Chris Evans and Hayley Atwell Help Fan Pull Off an Epic Proposal: Take a Look

Two were witness to the exciting moment during Salt Lake Comic Con over the weekend

Well, this is certainly a Comic Con moment to remember. 

Chris Evans and Hayley Atwell were the lucky witnesses of one man's wedding proposal at Salt Lake Comic Con over the weekend when the groom-to-be used his girlfriend's celebrity photo-op as the perfect opportunity to get down on one knee. 

Newly engaged Kelsey Jackson took to social media to share a pic of the proposal which sees her covering her mouth in shock as Evans and Atwell both look surprised and excited. 

"@HayleyAtwell @ChrisEvans thank you so much for being there. It was such a shock! You both are awesome! #iAmEngaged," Jackson captioned the pic in which she's dressed like Black Window while her future husband sports a Captain America costume. 

It was one of the most moving and beautiful things I have been witness to. Congratulations to you both. May you have a blissful future xx
