Another day, another nude Rihanna Twitpic.
The Unapologetic star took to Twitter Sunday and shared a black-and-white Instagram photo of herself without her shirt on (try not to act too surprised).
Ri-Ri sported tight black shorts, thigh-high socks and kicks in the revealing pic, and she has her back turned away from the camera as she glances seductively over her shoulder.
"#LondonNightLife," the 24-year-old stunner posted as the caption to the sexy shot.
The topless twitpic isn't the only controversial photo the "Diamonds" singer has tweeted as of late.
