Both relationships are notorious for being on-again off-again, and right now they're both in their off period... Rob Kardashian isn't currently with his baby-mama Blac Chyna, and Kylie Jenner is getting closer to her new bae Travis Scott.
Now, Blac and Tyga, who share a child together, have been spotted hanging out while partying in Miami together.
"In liv and they got blac chyna AND tyga in here lol," one witness tweeted during the night.
It wouldn't be totally outrageous for the pair to get back together, since they've dated before... but can you imagine how twisted that would become for the Kardashian/Jenner klan?!
We'd rather not even think about it.
