She also took the prizes - $1 million and headlining spot in Las Vegas.
Along with Darci, the other finalists revealed on Wednesday night were comedian Preacher Lawson, dog act Sara and Hero, singer and pianist Evie Clair, and singer-songwriter Chase Goehring. Her dancers looked ridiculous and actually distracted from her otherwise boring performance.
Host Tyra Banks said AGT had its biggest vote in history during final-round performances Tuesday night. That'd be hard enough for many a ventriloquist, but Farmer upped the ante by having them sing a duet.
"[My feelings were] all bottled up inside, because I felt so loved on my America's Got Talent journey... and it just all came out", she explained. In the video below, you can watch as both Oscar and Petunia sing the classic Beatles tune.
However, only 12-year-old Farmer, 9-year-old Hale and dance troupe Light Balance made it to the top 3.
The new "AGT" season 12 comforted Hale with a hug after the season victor was officially announced.
"You are just hands down incredible", judge Mel B said.
No wonder Darci Lynne Farmer is the frontrunner!
"It's not really common anymore, and not many people do it".
