Rihanna and Chris Brown rehab reunion, girlfriend Karrueche Tran totally in-the-dark? Model 'keeps it weird' on Twitter/Instagram while RiRi visits Breezy before 'wake n bake'

Apparently, the "love never dies" between Rihanna and Chris Brown. Maybe Chrianna's not "in love" anymore, but the two hip-hop/R&B stars can't seem to break ties. As Mstars previously reported, RiRi actually visited Breezy in rehab on Sunday (Dec. 8):

UPDATE: Rihanna & Chris Brown rehab 'reunion' REVEALED, never happened? RiRi NOT on visitor's list, Breezy doesn't want to see ex-girlfriend, Karrueche Tran remains loyal

According to the infamous gossip webloid MediaTakeOut.com, Rihanna recently visited her troubled ex-boyfriend Chris Brown in rehab. After all the drama the duo's been through in the past, Chrianna just can't seem to get enough of each other! Wonder what Breezy's current girlfriend Karrueche Tran must think?

There are few details circulating on the web surrounding RiRi's "secret" visit, but MTO reports that the "Diamonds" songstress arrived to the anger management clinic outside of LA on Sunday (Dec. 8). Here's an alleged photo of Rihanna "running away" from MTO's tipster during her little rendezvous (the image is VERY blurry).

Apparently the story is still developing, and a video is soon to come...

Breezy's currently in rehab to help curb his anger management issues - as several fans probably remember, Brown's violent domestic assault against RiRi back in 2009 is what ultimately led to their highly-publicized break-up. Since then, the "Don't Wake Me Up" crooner's been dating aspiring model Karrueche Tran, and their relationship seems to be going well. Tran continues supporting Breezy through this difficult time. But for some reason, Rihanna and Brown can't stop seeing or thinking about one another. They simply can't seem to move-on. What's up with that? Is Chrianna meant to be together in the end?

It doesn't seem like Tran's worried about the impromptu meeting, though. On Monday, Breezy's beauty tweeted:

@karrueche: "Being weird cause I'm bored and hungry."

She also shared this Instagram photo:

RiRi didn't mention her rehab visit on social media, either:

@rihanna: "More snow today.... #WakeNBake #ChroniclesOfaCaribbeanGal #iHeartNY."

If the Barbadian beauty did indeed visit her ex, the meeting was probably not in the least bit romantic. They were involved in a serious relationship for years - it's only right that RiRi would show her support!
