The posh youngster performs an acoustic version of Turn My Swag On for the panel, to a great reception from the audience.
Lauren, who has been singing from the age of three, explained before her audition: "When I was really small I would always sing to songs on the telly. I really want to be able to do it as my job."
Asked by David Walliams what she would do with the £500,000 prize money if she won, the adorable Lauren replied: "I’d have to go on a shopping spree. That would be pretty cool."
But in order to win, Lauren first needs at least three yeses from the judges!
