All eyes may have been on the stars of "Avengers: Endgame" at the movie's Los Angeles premiere Monday, but one couple in the crowd ended up stealing the show.
Shawn Richter attended the event dressed as Captain America with his girlfriend, Lisa Lower, fittingly paired as Peggy Carter, Captain America's love.
"He has always loved Captain America and it’s a favorite cosplay of his," Lower told InsideEdition.com. She added that she and Richter often wear matching costumes and think the story of Captain America and Peggy is "so sweet."
"We also have tattoos that say how we are with each other till the end of the line ... which is what Captain America says to his best friend Bucky Barnes," Lower added.
Richter said Lower flew from Portland to be with him on the purple carpet in Los Angeles. The Marvel fan apparently saw it as the perfect opportunity to mark a special milestone in their relationship.
When Richter got his chance, he got down on one knee and popped the question to his girlfriend.
"It's a little bit smaller than an Infinity Gauntlet, but I think you're gonna like it," Richter told Lower as he proposed on TV.
Lower said yes, pulling him in for a kiss and a hug.
"He's not one to go small, so I was thinking that his proposal would be something big. I had no idea that he was going to pop the question there. I was so excited to be at the premiere and so focused on that," Lower said.
In fact, their relationship began in a similar environment. The two met at a convention a year and a half ago, and they "instantly bonded over our love of pop culture," Lower said.
The newly engaged couple even got to meet a few superheroes at the premiere
"A total dream for a fan like me! Shawn had a goal of getting a picture with Chris Evans and I was really hoping to see Chris Pratt. This whole night has just been so surreal," Lower said.
