Karrueche Tran vs. Rihanna 'Beef' Continues After Chris Brown Baby Mama Drama: Twitter 'Hysterical' Amid Ex-Girlfriend Cheating Diss

Tough week for Karrueche Tran - the aspiring model just discovered that her on-and-off again boyfriend Chris Brown fathered a baby girl with another woman. Then Tran dumped her "Loyal" beau (for good)!

So - perhaps Hollywood "frenemy" Rihanna actually has the upper-hand this time?

Despite such heartbreak surrounding the situation, several Twitter fans are thoroughly amused (maybe even confused):

@RealityWivesUS: "It took a baby & not him boxing @Rihanna?"

@lucywallce: "Rihanna > Karrueche > Nia."

@Bossip: "Rihanna reading Karrueche's timeline like..."

@infimiz_one: "Rihanna somewhere reading this laughing like Woody woodpecker."

@yungfasa: "I know @rihanna glad she ain't @karrueche."

@Fameolous: "@karrueche Rihanna face when I asked her does she feel sorry for you."

@Copper_Soul: "So if Rihanna was FourFiveSeconds from wildin', Chris Brown was EightNineMonths just lying to Karrueche. Smfh."

@rihsleggz: "But @Karrueche remember this? You were crying over rihanna when you should have been crying over a baby."

@WrittenByTerry: "I had to deal with Rihanna, then Karrueche, now this baby... it's just... tew much."

Harsh stuff. But the "Pour It Up" songstress tries remaining nutural and mature. An alleged HollywoodLife.com insider reveals that she totally feels for Tran - no more shade!

"You know, [Rihanna]'s keeping it classy... This is not a time to throw jabs at another woman."

And RiRi was rather shocked to hear that Breezy's seedy infidelity actually resulted in a baby! But she truly hopes that things will eventually work-out:

"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... 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."

The HollywoodLife.com source concludes:

"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."

So, should #TeamKarrueche and #TeamRiRi finally unite against cheating boyfriends?
