What's a Rihanna sighting without a little scandal?
The controversy-courting pop star, who made headlines back in September when she was kicked off an Irish farm for baring too much skin during a raunchy music video shoot, wasn't shy about showing off her assets yet again when she hit Diddy's star-studded New Year's Eve bash in Miami this weekend.
Ri-Ri rocked a seemingly demure black Tom Ford long-sleeve, knee-length dress with a sexy keyhole neckline, black pointy-toe pumps and diva-red pout.
Pretty tame for this "S&M" singer's standards, right?
But the 23-year-old Barbadian beauty opted not to wear a bra and ended up flashing her pierced nipple for the cameras.
Was it an unintentional or a wardrobe malfunction?
Way to stay, er, consistent in 2012, babe.
