'America's Got Talent' Winner Grace VanderWaal Does an Adorable Simon Cowell Impression -- Watch!

If singing doesn't work out, Grace VanderWaal might consider Saturday Night Live!
The America's Got Talent winner performed on The Ellen DeGeneres Show on Wednesday, after delighting the daytime TV host with the story of what Simon Cowell meant when he called the 12-year-old singer the "next Taylor Swift" -- and the best part is, VanderWall told the story in Cowell's voice!
"He was just like, 'And that's what I meant when I called you the next Taylor Swift. Not because you look like her, not ‘cause you sound like her,'" VanderWaal adorably said in her best British accent.
"And he said it's because he's worked with Taylor Swift, and she's strong, and knows her opinion, and he said that's how he feels about me," she added.
The audience applauded the young singer, and DeGeneres had to congratulate her on her impression!
