"This is her way to show the world that she does not care. Rihanna doesn't want a big dress or boring old confetti. She wants to get married in her bikini and have a carnival atmosphere. They want it to be relaxed and fun, like a playground, and to celebrate with the people who have stood by them," a source said.
Rumours of a summer wedding surfaced last month with a source adding that the couple want tattoo artists, fire breathers and a near-naked waitstaff for the special day, as well as pre-rolled joints at the reception.
The 25-year-old announced her reunion with her former boyfriend in January, insisting that it is important that she is happy.
She has since said that Brown is not a monster despite his violent past. She sparked rumours of a wedding in February when she was seen wearing what appeared to be an engagement ring at the Grammy Awards.
