Olivia Olson (born May 21, 1992) is an American singer and actor. She is best known for her performance of the song All I Want for Christmas is You in the 2003 motion picture Love Actually. She also had a guest appearance on "The Tracy Morgan Show" in 2004.
According to director Richard Curtis' commentary in the music section of the "Love Actually" DVD, Olivia's singing was so perfect, they were afraid the audience would not believe an eleven-year-old could really sing like that. They had to train her a little so that her singing would sound more believable.
