The first photographs have been released by French sports brand Le Coq Sportif featuring its new model IU.
She is intended to reflect the company's fresh, fun and young outlook and was encouraged to put her own outfits together for the shoot, reports Soompi.
The South Korean singer and actress is heading a campaign being run with the strapline Le Le Le Begins ahead of the new school semester.
She is seen in the pictures published by Le Coq Sportif wearing casual clothing, accessorised with a black backpack.
"IU has selected shoes featuring a unique color scheme which consumers have already given them the nickname of 'IU shoes'," stated a spokesperson for the firm.
The brand has been in existence since 1882 when it was created in Romilly-sur-Seine, France.
Located in the country's champagne region, Le Cog Sportif has expanded from a single small hosiery store opened by sports lover Emile Camuset to a global company.
