Rihanna challenged to movie smackdown

Rihanna has been challenged to a girl fight by top stuntwoman-turned-action star Gina Carano.

The Haywire star is close to signing on for the latest Fast & the Furious movie and she can only hope that rumours suggesting Rihanna will play the film's bad girl are true.

Insiders suggest the R&B superstar is slated to join Luke Evans as the fast-paced action sequel's villains, and Carano can't wait for a potential "kickass fight scene" with the hitmaker.

The mixed martial arts champ tells Eonline.com, "I would love to see me and Rihanna go at it. That would be hot."
