Demi Lovato is set to be the new face of Topshop.

The 19-year-old star is in talks to be the new covergirl of the British retailer when the company opens a store in The Grove, Los Angeles, at the old site of Banana Republic.

A source told Hollyscoop: ''Demi is a huge fan of the brand, but nothing has become official quite yet.

''Demi Lovato is in negotiations to be the new face of Topshop, which is also known as Topman. It is a British couture clothing store that is coming to the US now.

''They are opening up a shop in The Grove, where Banana Republic used to be. They really want Demi and she has already sat down to go over figures.''

Kate Moss has previously modelled for Topshop - which has a spin-off brand called Topman, which caters for male customers and is now run as a separate chain - but the company has never used a celebrity as the face of their brand.

Demi has an ideal platform to be seen in Topshop clothing as she is currently a judge on US 'x factor' - alongside Britney Spears, Simon Cowell and L.A. Reid - a position she took up in May this year.
