The mystery of Rob Kardashian on social media continues.
After taking several weeks off from posting on Instagram, Rob shared an old photo of himself eating late last month.
He then skipped Kylie Jenner's 18th birthday party, only to post a number of weird messages on his Instagram account on the same day his sister celebrated a milestone.
Why did Kardashian honor Paul Newman? We may never know.
Now, Rob has shared a picture of Kanye West giving a cute smooch to his daughter, North West.
The reluctant reality star did not include a caption or a comment with the image, leaving his intention unknown.
The younger brother to Kim, Kourtney, and Khloe Kardashian has been famously out of the public eye for a number of years now.
He's scarcely been heard from or seen with his relatives ever since skipping Kim and Kanye's wedding in France in May of 2014 after he got into an argument with the bride-to-be.
After total radio silence, Rob made his big return to Twitter this past June to send messages of support Kim after news broke of her second pregnancy.
This latest posting certainly makes it look as if Rob is back to being on good terms with at least some members of his family... but who the heck knows?
