Michael's uncle said on Twitter the teenager had: "tried to hide the hurt when this happened but it was obvious that he was upset inside".
Hearing about the cruel prank, debating teacher Jenn Palomino said she was heartbroken, and determined to help right the wrong.
She contacted Miss Greater Salt Lake, Dexonna Talbot, and asked if she might be able to help salvage her student's homecoming expTalbot, who will compete for Miss Utah in the next few months, said she felt called to act the second she heard about the fake invitation.
"The second I heard about this, I knew I wanted to do something," she said.
"I automatically broke down into tears, because just thinking about the fact that someone would go out of their way to make someone else feel bad is so heartbreaking to me."
Holding a sign covered in Starburst - Michael's favorite candy, Talbot was filmed entering his high school classroom last week to ask him to homecoming - for real this time.
Standing up, he can be heard responding with an enthusiastic: "Sure!"
As the pair chat, Michael's classmates can be heard applauding the unlikely match.
On Saturday, Talbot shared photographs of the pair ahead of the big dance.

"Micheal you are one of a kind. I am so humbled by this experience. Bullying sucks and kindness ALWAYS wins."
Speaking to friends on Facebook, Michael's mother Jennifer said she still doesn't know who played the cruel prank on her son, but the family have chosen to focus on the positives.
"We don't know who did it, but to us it doesn't matter," she said. "Through this experience our sweet boy was able to have the time of his life."
"I just hope [the bullies] realize that you should [not] tear someone down to try and make yourself look cool."
