The 22-year-old star is launching the new scent in stores in the US in February and it will be sold for $49 for a 1.7oz bottle.
Speaking about the inspiration for the name Reb'l Fleur, she told PEOPLE: 'My grandmother in Barbados used to call me her Rebel Flower.'
The What's My Name singer added that she found it difficult to come up with the mix for the fragrance.
She said: 'Over the years, I layered many different scents to get something that was truly my own. But I wanted... something that said 'Rihanna was here'.
'Something delicious and special, a fragrance with subtle hints that linger and leave a sexy memory.'
