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? Hayley Atwell (@HayleyAtwell) September 27, 2015
Both Atwell, 33, and Evans, 34, took to their own respective social media accounts to tweet about the surprising proposal and share how thrilled they were to be a part of the moment.
"Today at #SLCC15 in the middle of a photo op with Chris and I, a man got down on his knee and proposed with a ring to his girlfriend," the actress, who has played Peggy Carter on both the silver screen and boob tube, wrote, adding, "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."
Wow....I've had the most amazing time at #SLCC15. I've been to a few conventions before but I've never had the opportunity to interact with? Chris Evans (@ChrisEvans) September 27, 2015
Likewise, Evans wrote, "Wow....I've had the most amazing time at #SLCC15. I've been to a few conventions before but I've never had the opportunity to interact with the fans on such a personal level. They shared some wonderful stories that I was honored to hear. I'm filled with a overwhelming sense of gratitude. Thank you to all of my loyal, sincere, loving, and passionate fans from the very bottom of my heart. You've reminded me how gratuitously lucky I am. #weareallconnected."
Congrats to the happy couple!
