Singer Leona Lewis has shown off her saucy side by donning a racy latex outfit for a kinky party with pals.

The Bleeding Love hitmaker shed her clean-cut image and embraced her inner bad girl for the bondage-themed birthday bash in Paris, France, where she wore a skin-tight pink dress baring her cleavage and a spiked collar necklace.

Lewis took to her Twitter.com page early on Saturday (03Aug13) to share photos of the risque event, including a snap of her posing alongside a man in a gimp mask with chains in the background.

Another saucy shot shows the pop star biting on a leather whip, while another depicts the birthday girl, Lewis' pal Aysha, receiving a lap dance from a scantily-clad female performer.

Sending best wishes to her friend, Lewis tweeted, "To my partner in crime, my homie, my best friend, my heart, my angel... from teen dreams to grown up realities, my ride or die, my bad a** b**ch. I wish you all the love and happiness in the world. from your b***h for life."
