The 25-year-old singer opted to go bra-less in a sparkling gold cape top which highlighted her slim figure, but nearly displayed a bit too much as she bent over to exit her car.
The top, which was split up the back, fell open to reveal Rihanna's toned torso, and numerous tattoos, as well as almost flashing her cleavage.
However, Rihanna appeared unconcerned about the near miss as she headed into the nightspot to watch her sibling, Rorrey - aka Gallest - perform.
Rihanna teamed the top with a pair of low-slung ripped jeans, turned up at the cuff, and holographic silver sandals.
