In February 2007, Lewis signed a �5 million ($9.7 million) contract in the US, with Clive Davis, founder of Arista Records.
Davis has been responsible for the success of Whitney Houston. Houston is reported to have said that Lewis will be an international star and has offered to mentor her.
Lewis will now release five albums worldwide through Davis's label, J Records. She celebrated her record deal by showcasing for several American music executives at the Beverly Hilton Hotel in Beverly Hills, California, where she sang "Sorry Seems to Be the Hardest Word", "Summertime" and "Over the Rainbow". One executive described her as "the lovechild of Whitney Houston and Mariah Carey".
A four-track download EP, "It's All for You", that she recorded before entering The X Factor went on sale online on 18 December 2006.
However, it was banned from several online stores by her record label, Sony BMG, meaning the single could not chart.
Lewis will reportedly make a performance on the current series of American Idol to help her launch her career in the US.
