Chris Brown Baby Mama Drama, Rihanna 'Shocked' Amid Karrueche Tran Cheating Scandal: Instagram 'Thot' Nia Gonzalez & Ex-Girlfriend Friends!

Fans are going crazy - rumors suggest that Chris Brown "secretly" fathered a daughter with infamous Instagram model, Nia Gonzalez! The little girl is only nine-months-old... which means Breezy perhaps cheated on longtime girlfriend, Karreuche Tran during the short-lived fling (which resulted in a child).

So - what does ex-flame Rihanna think about all of this explosive baby mama drama?

An alleged HollywoodLife.com insider reveals that RiRi was initially shocked (of course), but the Barbadian beauty believes that 25-year-old Brown will certainly do the right thing:

"Rihanna is shocked and had to read the reports four times before it finally sunk in... But first things first, and that's that if it's true, Chris will be a good father and take care of his little girl."

The source continues:

"That's a big responsibility and something that requires a lot of work, energy and love... She wishes him all the best in this new and very important chapter in his life."

What a mature reaction! Maybe hooking-up with (older) Leonardo DiCaprio helped Rihanna officially move-on from her troublemaker ex.

Still, the 27-year-old #BadGal is just happy she got out of the relationship in time (poor Tran!):

"Rihanna's been through it all with Chris. This is the type of situation that some women would lose their minds over and end up doing something very foolish," the snitch concludes. "She's thanking everything around her that she's not in this position."

Interesting fact - the infamous gossip webloid MediaTakeOut.com claims that the "Pour It Up" songstress is actually "friendly acquaintances" with 31-year-old Nia!

Meanwhile, the "Loyal" crooner remains completely silent on Instagram (probably preparing to make his next move).

It's no secret that Tran always wanted to start a family of her own (probably with Breezy). How heartbreaking - will the couple finally break-up for good now?
