A star is born? Barbadian hitmaker Rihanna has been cast in her first starring role, Star Magazine snoops spill in the mag’s Feb. 22 issue.

The “Umbrella” star has landed the lead role in About Face, which Star claims will see Ri-Ri as “a fashion designer who has to change her ways to win the heart of the man she loves, similar to the 1975 Diana Ross film, Mahogany….”

While The Bajan Mama is eager to add acting to her resume, Hollywood execs aren’t quite sure the beauty’s got the acting chops to pull off the role without landing a Razzie nod for Worst Actress! One tattle tells the tab: “No one is sure she has any acting skills. She’s a bit stiff and has to learn how to emote more…No one wants another Madonna on their hands — someone who can sing but can’t act.”

Rihanna has been asked to “quietly” enroll in acting classes.
