Rihanna Rocks “American Idol” Finale

It’s always a treat when she takes the stage, and last night (May 23) Rihanna brought her A-game to the “American Idol” finale.

The “Take a Bow” songstress was all about showing off her fabulous form in an Adam Selman belly-bearing top and sexy skirt as she worked the crowd into a frenzy.

Always a fan of changing up her coif, Ri-Ri was sporting her new dreaded hairdo as well, giving her look the island vibe.

When asked via Twitter what made her choose the hairstyle, Rihanna tweeted, “they’re HOT!... since I was 14 but mama Fent’z wasn’t havin it! Hehe!”
