Furious 7 star Ronda Rousey is trading in her mixed martial arts gloves for another major film role after landing a part in comedienne Tina Fey's new movie.

The female fighter, who is still nursing her wounds following her first defeat in the ring at the hands of Australian Holly Holm last year (15), is slated to join Fey in Do Nothing B**ches - a phrase Rousey has often used in her own motivational speeches.

Rousey, who also appeared in The Expendables 3 and Entourage, will play a tough trainer to a group of slacker women in the new comedy.

The MMA superstar is also reworking classic movie Road House, taking on the bouncer role the late Patrick Swayze played in the original film.
