We're not sure what this means for the couple, but last time Rob did an Instagram purge, he claimed it was due to privacy.

In March, the 29-year-old wrote, "Chy and I are not broken up we just feel like it would be a lot healthier for our relationship if we kept a lot more to ourselves. It's impossible to have a positive relationship with so much negativity from the media and outsiders and we would appreciate it if everyone respects that."

Too bad that doesn't explain his unfollow this time around! For a closer look at Rob and Chyna's whirlwind romance, scroll through the gallery below.
