It looks like there's a rumor going around between rapper Drake and pop star Chris Brown if they're creating some big plan to hurt Rihanna.

Drake's Song Implies Cheating Rumors?

The reported ex-boyfriends of the Diamonds singer are apparently working in the music studio together, which caused a lot of heads to turn. Considering that the two guys are both connected to Rihanna, people may have wondered if the reason for working together is to create some sort of vegeance on their ex. But as it turns out, there are no plans like that, according to Rikki Martinez from Power 106.

On Tuesday, Martinez tweeted, "On the phone w/Tyga earlier. Drake was in studio w/him & ChrisBrown to be on the next Fan of a Fan project. There's no Rih diss in the works."

Drake Didn't Support Rihanna At iHeartRadio Music Awards?

There was a recent report from Urban Islandz where it was said that Rihanna, whose real name is Robyn Fenty, might have her own problems, and Drake apparently thought Brown was responsible for that.

"Drake thinks Robyn has a lot of self-esteem issues and he blames Chris for that," a source said. "He feels like she is afraid of a commitment because of her trust and self-esteem issues. But she is one of the most confident gals I know so none of us really believe that. Drizzy acting like a bitter ex."

This might also cause some fans to wonder if Drake really does blame Brown considering they are, after all, said to be working together in the studio. But as of now, it seems like whatever they're doing is strictly professional.
