Rihanna has unveiled a trailer for her upcoming Styled to Rock series.

The reality TV show originally aired in the UK last year as a number of fashion designer hopefuls created outfits for music stars.

An American edition of the series will air from November 5 in the US on the Style Network and Rihanna, who acts an executive producer on the show, has teased it with a new video.

The clip sees Rihanna plug the series - and it also reveals that Pharrell Williams will star as a judge.

The UK edition of the show meanwhile featured Girls Aloud star Nicola Roberts help judge the talent.
