Following Levine's sweet tweet, ET caught up with Hunt on Saturday, giving us an update on how the surgery went.
"The surgery went well, but I'm still in pain," he said. "But seeing that video made my whole life! Adam Levine has been my favorite singer ever since I can remember. I sang that same song for my sixth grade talent show."
Hunt also told ET that although he's "never gotten the chance to meet" Levine, he did attend a Maroon 5 concert for Christmas in fourth grade. If he does meet his idol someday, he already knows what he'll tell him!
"I think I would cry first, and then freak out," Hunt gushed. "I would just tell him how much everything about his music has helped me."
Hunt later re-tweeted Levine's message, writing, "I can't breathe, oh my god. Thank you so much, I am your number 1 fan. This is CRAZY."
According to the description on the video, Hunt was recently diagnosed with cardiomyopathy, a disease of the heart muscle, which will require him to undergo two surgeries. He underwent his first surgery on Tuesday, and his next will require a heart transplant.
In addition to touring with Maroon 5, Levine has also been busy with fatherhood, as he and his wife, supermodel Behati Prinsloo, welcomed their first child, daughter Dusty Rose, in September.
During an interview with On Air With Ryan Seacrest earlier this month, Levine revealed his parental "instincts" have already kicked in.
"I've been a parent for three weeks, what do I know?" he joked. "I don't know anything. But it's kind of part of the beauty of it, honestly. There are a lot of instincts, a lot of things that kind of kick in and switch on. It's a beautiful experience."
