Karrueche Tran vs. Rihanna Jealousy? Chris Brown's Girlfriend Slams 'Don't F*ck With Broke B*tches' Instagram 'Hater' Amid Cheating Scandal & Twitter Diss

But according to the infamous gossip webloid ThyBlackMan.com, RiRi and the "Loyal" singer were actually spotted "kissing" at a popular LA nightclub just last month (October 15). Meanwhile, Breezy's still dating on-and-off again model girlfriend, Karrueche Tran.

Just days later, the "Diamonds" songstress re-tweeted this quote from one her best-selling hits, "Only Girl (In The World)":

@rihanna: “Want you to make me feel like I’m the only girl in the world."

The lyrics were originally posted by a fan whose profile pic showed the Barbadian beauty "making-out" with her former hip-hop lover.

She also said this on Instagram:

"There's a difference between having a real relationship and just being together because that's all you're used to. There's a difference between meaning your 'I love yous' and just saying them every night because 'that's what you do'. There's a difference between being together and wanting to be together. It's a relationship, not a routine."

Interesting...

And more recently (on November 10), the 26-year-old pop sensation shared this rather cryptic tweet:

@rihanna: "If you start feeling like a 'chore' to someone, you probably are!"

Ouch - was this a direct blow aimed at Tran? Maybe her romantic status with Breezy is currently on-the-rocks...

Apparently, the post has since been deleted. Somewhat odd, considering RiRi blasted the same message back in October 2012, and that post still exists online...

Perhaps ThyBlackMan and similar gossip outlets are simply re-hashing old Chrianna news in order to stir-up some unnecessary drama?

Menawhile, Tran's relationship with Brown seems to be doing just fine. In fact, the exotic beauty just rented a luxury home in LA - for a whopping $4,600/month.

As TMZ points out:

"It seems like a hefty price to pay for someone with no full-time gig... but she's been scoring some lucrative appearances at nightclubs recently -- thanks to Chris, of course."

Ha - maybe that's why she ignores the nonstop cheating buzz?

Not to mention this seedy "man junk" photo that recently leaked online...

So what's up - is Breezy better off with Rihanna, or KT?
