WTF Is Happening Between Rob Kardashian and Karrueche Tran?

Rob's latest Instagram activity is very suspicious.

Rob Kardashian, you are such a mystery. Well–your social media presence is, at least.

Us Weekly reports the sole Kardashian brother created excitement on Instagram Tuesday night, and it involved Chris Brown’s ex-girlfriend Karrueche Tran. Yup.

OK, so here’s what went down: Rob uploaded a since-deleted Instagram photo of a text conversation he had with Ms. Tran, which included a selfie she sent him. Thanks to the sleek peeps at Us, we still have that handy-dandy snap:

“I like when she send me pictures,” Kardashian wrote in the caption, along with a few heart emojis. (Why did he have to delete it?! ?)

Even cuter, Rob has Karrueche’s name is his phone as “Karroooooochieeee.” Do we smell a cute pet name, or are we just getting excited?

Perhaps it’s the latter, because Rob later changed the photo caption to shoot down any speculation K and he are dating. “Yall dumb af,” he wrote. “I been Friends with Karoooooch since high school. F–k outta here with your negative s–t.” (Again, he deleted all of this from his Insta.)

We understand what you’re saying, Rob, but we’re not buying it. The heart emojis? The nickname? The quick delete? It all seems very “secret couple” to us. For now, though, we guess we’ll hold our horses.

Annnnd secretly pray y’all crazy kids get together officially!
