Rihanna had yet another wardrobe malfunction in Paris, going braless and exposing her nipple ring. She's had a lot of those lately-and apparently, even her mom told her off about her risqué Instagram photos!

Rihanna was in Paris on her Diamonds world tour, and took yet another sexy, semi-nude photo-this time in front of the Eiffel Tower. The location makes it a bit classier, perhaps?

RiRi posed with fans in front of the tower, showing that her sheer white shirt decidedly didn't have a bra underneath.

Wardrobe malfunctions are becoming pretty common for RiRi.

MediaTakeOut posted pics of the photo zoomed in, making her nipple ring easier to spot. See them here

Rihanna's having a bit of trouble holding it in these days...literally. We've now seen various parts of her anatomy popping out of various garments-- it seems there's a wardrobe malfunction at least once a week.

Last week, Rihanna flashed her crotch on stage in Istanbul, Turkey.

During a recent concert in Istanbul, Turkey, RiRi had a wardrobe malfunction when she flashed her crotch. Yup, yet another one. The "Diamonds" singer was on stage May 30 and wearing a sheer skirt over a bikini top, short-shorts, and thigh-high boots. And if the outfit itself wasn't revealing enough, the paparazzi got an angle that Rihanna probably didn't realize.

Paparazzi standing underneath the stage took photos going straight up her crotch-revealing a bikini wax.

Legend has it, Rihanna loves the pain of getting Brazilian waxes.

Rihanna's currently on tour in Europe....and we have a feeling we'll see some more wardrobe malfunctions as the shows progress. Stay tuned.
