Karrueche Tran vs. Rihanna Beef, Chris Brown & Ex-Girlfriend Back Together? Instagram 'Puppy Love' Revenge After Chrianna Reunion 'Threat' [PHOTOS]

Rihanna keeps "playing" with the emotions of both Chris Brown and Drake. Apparently, the "FourFiveSeconds" songstress reunited with these two ex-lovers at Coachella just last month. But she ultimately began spending more time with Breezy. That supposedly caught the attention of ex-girlfriend Karrueche Tran - because rumors now suggest that she's back together with Brown for good!

Chris Brown Single? Rihanna vs. Karrueche Tran 'Back Together' Instagram Shade: 'F*ck Your Weak A$$ Side Story' Diss

The 27-year-old Barbadian beauty and 25-year-old "Loyal" crooner were both spotted partying at rapper Travis Scott's birthday bash earlier this week. Chrianna was not photographed together, but apparently their relationship's getting quite flirtatious once again...

But maybe Tran wants to prove that she's still Breezy's top chick (despite their recent bitter break-up), because she recently shared this viral snapshot on Instagram:

karrueche: "hi baby."

So - according to the infamous gossip webloid MediaTakeOut.com, that adorable bulldog pup on the right actually belongs to Brown. Do MstarsNews fans see the resemblance?

Obviously this means that the aspiring model was chilling at Breezy's house - just a few days after his "romantic" reunion with RiRi. Interesting...

Does this mean that Brown ultimately ran back into the arms of Tran instead? Also, the tattoed hand in the above pic does actually belong to Kae (not her former beau). Here's what some fans are saying:

leaveittotyra: "Chris Brown doesn't have tattoos on his left hands idiots... Let her live, damn..."

iamabetodd: "Girl... I'm unfollowing you."

kdott23: "I actually had faith that you moved on and proved to the world that you don't need a man for nothing, and also showing us women to never go back to a cheater and find someone who's willing to cherish you and love you and not hurt you - but youre sinking into a hole and going back to the same situation... pray my love."

amanda_couldnt_have: "I see a sneaker print of where Chris was standing right near Athena! Yall see it? This doormat is back with Chris. I knew it!"

Maybe Chrianna really isn't a "thing" anymore... Sound-off in the comments below.
