Kellie Pickler and pro partner Derek Hough won the 16th season of Dancing With the Stars on Tuesday night, beating out Zendaya and Val Chmerkovsky and Jacoby Jones and Karina Smirnoff.

Pickler and Hough had a combined team score of 94 for both nights of the final competition, and Pickler, who rose to fame on American Idol, clearly wasn't expecting to take home the top prize. "Oh my God!" she exclaimed when her name was called. "This is amazing, oh my God!"

"I never thought I'd do this show," she told Us Weekly on Monday evening. "Part of me wanted to, but I was honestly scared to. My grandpa talked me into doing it. It's his favorite show -- and he wanted me to have Derek as a partner! I'm kind of nervous that whoever wins tomorrow night, my grandpa might run out there and snatch the Mirror Ball trophy anyway!"

Congrats!
