At Lauren Hernandez's graduation party, she surprised her mother's long-time boyfriend with a heartfelt gift: adoption papers.
Lauren tells ABC News, "I was only with my biological father every other weekend, but I was with Joe almost every day."
Her mother, Sally, has been dating Joe Iosco since Lauren was one year old.
"He did things for me and he took me places," she added.
Iosco explains, "As the years went by, I not only fell in love with Sally but I fell in love with Lauren as well."

"I'm asking Joe to adopt me!" Lauren announces to family and friends in the video. Iosco, overwhelmed with joy, crumples to the ground. Between tears, he manages to get out a "yes."
