British website The Daily Mail Online posted a story, which includes snaps of the Umbrella singer getting into her limo after a London party, reports the Daily Telegraph.
Rihanna had spent a gala time at the Mahiki nightclub where she had even held a secret preview of her latest album, 'Rated R' for her fans but her exit from the bash turned out to be a fiasco.
The 21-year-old starlet, who wore a mini-dress and shoe-boots, left the party less than gracefully. Unable to carry herself, she gave a glimpse of her dimpled upper thighs and then the camera clicked her underwear.
Once she even landed horizontal in the rear seat of the car before she finally got a hold over herself. Rihanna had been partying at the nightclub with Jay-Z and his missus Beyonce.
