Rob Kardashian and Blac Chyna Spark Break Up Rumors

Just days after proclaiming his love for Blac Chyna, Rob Kardashian opted for the Instagram nuclear option of deleting every single one of his posts. Chyna also posted -- and then deleted -- an Instagram image that seemed to indicate she was single again.

So have the two broken up?

After Kardashian wiped the slate clean on his Instagram account over the weekend, with no explanation offered for the deletions, he posted one new photo of a birthday cake. He captioned the seemingly random pic, "Cake cake cake cake cake March 17th 🍀🍀🍀," referring to the date of the 28-year-old reality star's upcoming birthday.

As for Chyna, her deleted Instagram post, which only stayed up for a few hours, was a photo of different woman with overlaid text that read, "When you just get out of a relationship and your Hoe friend welcomes you back into the World of Hoe." That sounds a little bit like the 27-year-old model is single again, doesn't it?

Despite the cryptic social media messages, as of Sunday afternoon, the two still follow each other on Instagram, so perhaps there's still room for the couple to work things out.

The odd social media behavior just days after Kardashian declared his love for Chyna. Though it's one of the Instagrams that has now disappeared, the reality star had written, "Love this woman right here, so f**k y'all with your negative comments!!"

That post was followed up the next day with a more cryptic message reading, "It's okay to live a life others don't understand. That's the whole point of living. To live YOUR life. Not everyone will understand you."
