Pop princess Rihanna is planning an unusual product launch to follow her line of umbrellas - she wants to create her own underwear collection.

The 20-year-old singer launched her own collection of the colourful totes this year following the success of the summer anthem Umbrella - but she admits she feels under pressure to follow in the steps of other Hollywood stars and build her own brand.

However, the star wants to opt for a more seductive line of apparel from her fellow stars.

She says: "There might be a clothing line on the horizon, maybe underwear."

She has lent her name to brands in deals with cosmetics giant Clinique, retailer H&M and Secret deodorant. - Wenn
