Brie Larson looks stunned after fan PROPOSES to his partner during Comic Con photo op: 'Much love to the happy couple!'

Brie Larson is a 'changed' woman after attending her very first Comic Con in Chicago over the weekend.

During one of her many photo ops during the meet-and-greet portion of the ACE Comic Con Midwest, a man, identified as John Chambrone, got on one knee to propose to his partner, Richard Owens. 

And Larson's stunned and excited reaction to the proposal was caught on camera and shared in a series of photos on Twitter.

The person who posted the pictures pointed out the obvious and wrote, 'Brie's reaction to this proposal is the most wholesome thing.'

It didn't take long for the actress to retweet the images and added, 'Ya'll I was present for a proposal and I am CHANGED. Much love to the happy couple!!!!' 

The four snaps serve as sort of a time sequence: the first three show Chambrone on one knee as he presented his engagement ring, much to the surprise of his partner and Larson. The Academy Award-winner's eyes bulged and her mouth was wide open with excitement. 

The fourth and final snap of the series shows the couple sealing their commitment to be married with a passionate kiss as their superhero star stood behind them, still looking stunned.

Later on Saturday, Chambrone, the man who got down on bended-knee, took to Facebook in an open letter and explained why he choose to 'ambush' Larson with the proposal.

First he thanked her for making herself available to her fans, then he apologized for for the ambush.  

He then went on to say how Carol Danvers has been his 'favorite character in the comics' since he was a kid.  

'From her debut as Ms. Marvel, through her Binary and Warbird years and finally full circle as the mighty Captain Marvel, I have followed her adventures and your portrayal of her was so on point! I met Richard earlier this year and once our eyes locked for the first time, we both knew we found our soulmates.'

'Looking forward to how higher, further and faster my love grows daily with Richard Owen! THANK YOU!!' he concluded.
