Standing side-by-side with her adorable stuffed rodent pal, Farmer first demonstrated her ventriloquism skills with a cute conversation in which Oscar professed his love for Mel B, even though Farmer explained that there might be a problem with that.
"I know! She's afraid of mice," Oscar lamented.
"Well, Oscar, I think your bigger problem is that she's a human and you're a mouse," Farmer replied.
"I didn't think that would be an issue. I mean, Heidi was married to a seal," Oscar shot back, obviously joking about fellow AGT judge Heidi Klum's former marriage to the singer Seal, who was a guest judge on last week's episode. "So, I decided to sing her a song to tell her how I feel."
Proving that her talents are multi-faceted, Farmer managed to sing, as Oscar, an amazing rendition of the Jackson 5 hit "Who's Loving You?" It would have been an amazing performance even if Farmer was just singing it herself, but she sang it with her mouth closed and in Oscar's voice.
Getting back to the performance, Cowell was incredibly supportive of Farmer 's amazing talents. The often acerbic host told the young performer, "Get ready for the big time, because it's coming your way."
