19 year old Charlotte Rundle from Newquay is through to the next round of X Factor. Together with Simeon Dixon, she performs as MK1.
The duo say they are "delivering the underground to the overground" and think the time is right for their mixture of dubstep, pop and hip-hop to be a success.
More than ten million people will be watching the X Factor tomorrow night, when the live shows are aired for this first time this series.
Our reporter Kathy Wardle has spent the day meeting the family and friends of Lottie Rundall (also known as Charlie) who is part of the band MK1.
