Rihanna on New Year's Eve Twitter.com

Rihanna has a great body and she certainly knows it. The proof - she has never really thought twice about showing it off, in revealing costumes. This time, however, the Barbadian singer has gone one step further, showing off a body piercing at P. Diddy's New Year party in Miami.

The singer wore (and looked very comfortable in) a black lace dress that left very little to the imagination and displayed a nipple ring.

The 23-year-old must have decided to welcome the New Year in her own very special way and seemed to enjoy every bit of the party held at the rapper's Miami estate.

Sunglasses and Advil... Lastnight was mad real! a content Rihanna later tweeted.

The We Found Love singer, who took a break from her holiday in the hometown of Barbados, to fly to Miami for the party also tweeted a picture of herself, along with a friend.

She posted: @iAmQueenLatifah just bust out @ @iamdiddy party singing #G4L !!! I cud cry!!! Ok I'm really crying!! My year started SO right!!! #MAJAH.
