Rihanna Chris Brown Wedding In The Works? 'Swagger, Bling & Sin' Theme Says Source

Rihanna, who turned 25 on Feb. 20, is reportedly secretly engaged to Chris  Brown and in the process of planning to get married in her hometown of Barbados in late July, according to rumors.

The Bajan beauty was seen sporting a single band diamond ring on her wedding ring finger for the first time when she performed her single Stay at the Grammys on Sunday, Feb, 1. She was seen sporting the ring again during her birthday trip in Hawaii.

Now, the couple are discussing specifics about the details they would like to include on their special day to make it more exciting for guests, an insider has revealed.

"They want tattoo artists, fire breathers and a near-naked waitstaff," a source told Star magazine. Rihanna, who has never been shy about flaunting her love for marijuana, is talking to Brown about having "pre-rolled joints at the reception" so their guests can also enoy the special rolled-up cigarettes she favors.

The planned summer wedding will be "all about swagger, bling and sin," the source added. "They want to celebrate their relationship with people who believe Chris has changed."

Rihanna was seen with Brown, 23, on her birthday taking a stroll together on a Hawaii beach. She was holding a rolled up brown cigarette as she sported a bright pink bikini with fishnet cover-up. Brown was wearing an athletic sports jersey and red swim trunks that could barely stay on.

Later, they rode the back of a limousine together around the tropical island.

"Pour it up pour it up! #birthdaybehavior," she wrote on Twitter with a photo attached of herself sitting on his lap.

Rihanna shared a series of personal polaroid-style pictures the next day on Thursday that were taken at her private birthday party that was thrown for her on Wednesday night. The intimate event reportedly took place in a hotel room at an unknown resort in Hawaii.

In one photo, Brown is standing behind her and nuzzling her neck as she smiles for the camera. In another, he is holding the small of her waist as he leans his face against the side of her arm. Rihanna also shared pictures of her birthday cake which had icing in the Jamaican Rastafarian colors of red, yellow and green and was decorated with gold marijuana leafs. She also posted one of her birthday gifts of a Goyard handbag.
