Fashion week organizers listed the pop star on its official calendar of fall previews as they sent out registration materials on Thursday to the editors, stylists and retailers who cover designer collections.

The 24-year-old's first collection of clothing and accessories will be shown Feb 16. Items will be available in River Island stores in Great Britain, and in the United States and Japan at Opening Ceremony starting on March 5.

Rihanna said in a statement that an appearance at fashion week is "a dream come true".

She already has another fashion commitment this year: She signed on to executive produce and star in the Style network reality series "Styled to Rock".
