Taylor Swift and Rihanna appeared to swap hair styles for the American Music Awards.

Taylor ditched her trademark curls for a straight do, and Rihanna swapped her new long, straight locks for a curly ‘do.

Both stars picked up an award. Taylor was named Favourite Female Country Artist and Rihanna bagged the Favourite Female R&B Artist.

As far as their outfits go, Taylor, 20, won our best dressed award for her Collette Dinnigan mini-dress. We weren’t crazy about 22-year-old Rihanna’s gown from the Ellie Saab Haute Couture collection – at least it matched her hair?
