Drake Refuels Chris Brown Beef, Blames Ex For Rihanna 'Low Self Esteem' Break Up? RiRi Flaunts New Septum Piercing Amid Big Sean Dating Buzz [PHOTOS]

Apparently, Drake still has a "thing" for former flame Rihanna. So, why did the two ultimately break-up? Again, Chris Brown's all to blame!

An alleged insider for UrbanIslandz reveals:

"Drake thinks Robyn has a lot of self-esteem issues and he blame Chris for that.He feels like she is afraid of a commitment because of her trust and self-esteem issues."

The snitch suggests that Breezy lowered RiRi's self esteem during their troubled rromance, and now the "Pour It Up" songstress can't main a normal, healthy relationship.

However, the source explains, "But she is one of the most confident gals I know so none of us really believe that. Drizzy acting like a bitter ex."

Do Mstars readers agree - is Drizzy simply jealous, because such Chrianna drama will never actually simmer down?

Meanwhile, rumors suggest that the Barbadian beauty's currently working with rapper Big Sean. In fact, they might be getting close in AND out of the studio...
