R&B star Rihanna is setting her sights on a foray into acting - in a bid to expand her international appeal. The 20-year-old singer's hits are a staple on some of Hollywood's biggest soundtracks, but she admits she would like to grace the screen herself.

And she insists she is unphased by the stigma of becoming a singer-turned-actress.

She says, "I don't know how good I'll be at it, but it's something that I want to try."

The "Umbrella" hitmaker is reportedly set to star in upcoming film Mama Black Widow - the story of a black family's migration from the South in the 1930s.

The film, currently in pre-production, is said to co-star Kerry Washington, Mos Def and Macy Gray.
