Earlier, we told you guys about Nicki Minaj making the announcement via Twitter that she will not be joining Rihanna‘s upcoming concert tour. Well we are getting word via several media outlets that there was some drama going down behind the scenes. Apparently, Rihanna was not too happy when she heard that Nicki Minaj was going to join the tour simply because she felt that the hot female rapper would steal her shine during the tour.

An insider explained: “No one [in Rihanna’s camp] is panicking yet, but there is DEEP concern that Rihanna has peaked, and is on the downside of her music career. Nicki [Minaj] was brought in to sell tickets, but Rihanna did NOT want her on.” Someone close to Young Money allegedly said: “Nicki is not an opening act, and we would never put her out there like that.”

Ultimately, Rihanna demanded that Nicki Minaj be dropped from the tour and when Nicki got word of this move, she personally reached out to Rihanna and let’s just say it wasn’t a very pleasant conversation…

The insider also said: “I only heard one side of the conversation, but [there] were a lot of curse words thrown back and forth.”

Wow! We’ll keep you posted as more info unfolds.

Do you think Rihanna has any reason to be jealous of Nicki Minaj, and vice versa?
