Rihanna showed her naughty side this Christmas as she got decked out in sexy red lingerie for her friend Leandra's holiday party. She treated fans to some sexy snaps on her Instagram, striking various poses in front of the tree and on the bed, while also hanging out with her best friend Melissa Forde.

The "Pour it Up" singer also showed a close-up of her Christmas nail swag, which included a different design for each finger, which Rihanna said looked like she "just fingered Ke$ha." Check out all of the exciting photos of Rihanna in the above slide:
