Los Angeles: R&B singer Rihanna is the cover girl of the April edition of US Vogue.

The popstar is the new cover girl for Vogue which celebrates the 10th anniversary of the magazine's Shape issue.

She is pictured in a sheer floral dress with flowers covering her modest on the cover of the fashion bible, a magazine reported.

Her bright red hair, which partially covers her face, is complemented by bright red lips against the blue sunset background in the cover shot by Annie Leibovitz.

Rihanna is renowned for her outlandish wig collection and her 'hair architect' recently divulged his ideas behind the star's ever-changing hair.

"It's about the style you want first. You have to have your vision, then you go and find the piece," said the expert.
