The Talk That Talk singer was thought to have rekindled her romance with her ex, who she split from in 2009 after he admitted assaulting her, and the pair have been fuelling the speculation by tweeting pictures of each other and themselves together.
The Sun reports that Ri-Ri has now gone one step further by having a tattoo of the word 'Breezy', which is what many of the RnB singer's fans call him.
A source said: "She got it to symbolise her commitment to him.
"Now the world knows they're back together, they're determined to make it work."
Rihanna is already thought to have around 18 etchings, including a Sanskrit prayer on her hip and a gun under her arm.
