According to TMZ, both stars have been seeing each other for 3 months but nothing is exclusive yet!
New photos from the singer's 27th birthday bash, which the actor helped organize, seem to confirm both stars are seeing each other.
According to TMZ, eye witnesses at the party in New York on February 20, admit that the couple was involved in plenty of PDA (Public Display of Affection) that night.
Rihanna was said to had been the clingy one, who couldn't keep her hands off the 'Titanic' star and followed him everywhere he went.
As one source put it, "she's the baddest bitch in the party, but she's following him everywhere."
The site claims the stars have been seeing each other for about 3 months yet nothing is exclusive.
However, it's still unclear if RiRi and Leo are trying to fool the press and fans as its also reported that the 'FourFiveSeconds' singer is actually dating Leo's good friend and nightclub owner, Richie Akiva.
