When Rob Kardashian and Blac Chyna first went public with their relationship in January, fans were stunned at the news of this most unlikeliest of couples.
But the romance moved forward at warp speed - the two moved in together, appeared to be inseparable and posted about each other on social media constantly.
But now, it looks as though the duo have called it quits for real.
Rob deleted all of his photos on Instagram, many of which referenced his girlfriend.
Conversely, Blac posted a meme to the social media platform, reading, "When you just get out of a relationship & your hoe friend welcomes you back into the World of Hoe."
She captioned the photo with an anguished face emoji and a laughing-so-hard-I'm-crying emoji.
A source confirmed to Us Weekly that the couple did indeed break up, but senses that it may not be permanent.
“They were moving too fast,” the source told the magazine. “They had a fight about how much time they had been spending together but they’ll be back."
"This is a relationship in the fast lane," the source added. "It all moves fast, so the breakups are dramatic too, like the relationship. They could be back together whenever, it’s so dramatic.”
This indeed is stunning news. While the pair was controversial, particularly among Rob's family, nearly all reports have claimed that they were very happy together.
Just three days ago, Rob posted a photo of Blac sleeping, proclaiming his love for her and including a big "f**k y'all" message to any haters who disapproved.
However, many detractors believed Blac was using Rob for fame and that he was using her to get back at his family.
Rob's sister Kylie Jenner, who is dating Blac's baby daddy and ex-fiance, has been feuding with the eyelash designer for more than a year.
We'll keep our eye on Instagram for any signs of a romance rekindling.
