She said backstage: "Since being a child I've had a background in dance. I took ballet classes and tap classes. I'm terrified about performing in front of so many people today. I think it's being out of my normal space."
Just before performing, 27-year-old Beatrix admitted she was "a bit terrified" to Cowell, who has been attracted to previous erotic dancers on the show.
Cowell said to Beatrix: "Oh, you've got nothing to be afraid of."
