"America's Got Talent" star The Horse -- who famously got his nuts smashed on the show -- gave his girlfriend some wood in a creative proposal of marriage.
Zac Gordon tells us he proposed last weekend by placing the ring in a specially made Groot statue. replicating the popular character from "Guardians of the Galaxy."
Gordon says he didn't even have to pay for it ... his friend crafted it free of charge. Horse did pay for the chainsaw.
For the record, his fiancee said yes. The alternative would have been for her to kick him in the nuts.
