Watch Ariana Grande effortlessly perform a hilarious surprise song about being very, very tiny on late night: 'I am a human baby carrot. I am a lady Pikachu!'

The late night host introduced the Grammy winner to the stage and declared, “Your test tonight, if you choose to accept it, is to sing a song you’ve never seen the lyrics or heard any of the music before.” Grande simply replied, “It’s too late. I can’t turn back.”
