All the Times Rob Kardashian Made Us Say 'Um, What?!' on Social Media

It's no secret Rob Kardashian has a reputation for airing his frustrations on social media, whether that means going on mini Twitter rants (not unlike brother-in-law Kanye West) or deleting all of his photos on Instagram.

As fans and followers alike try to make sense of all this (including the expectant dad's recent dig at sister Kylie), we're taking a look back at all the times the Rob & Chyna star had everyone feeling totally confused on Instagram and Twitter.

WHEN BLAC CHYNA DEBUTED ON HIS INSTAGRAM

What does it all mean? In the photo seen around the world (wide web), Rob and now-fiancée Blac Chyna made their couple debut on Instagram in December 2015, with the model and the youngest Kardashian sibling posting a snuggly pic on their respective accounts – leading followers to collectively freak out.

WHEN ROB TOOK A BREAK FROM POSTING ANYTHING ON SOCIAL MEDIA

After an influx of Chyna pics found a home on Rob's Instagram feed, the sock mogul stopped posting altogether, for a total of nine weeks.

WHEN ROB RETURNED TO INSTAGRAM

Talk about a power move! After his brief hiatus from the social media platform, Rob returned to Instagram in January 2016 – the same day sister Khloé spoke out about her brother's recent diabetes diagnosis – by posting a meme about losing the $1.6 billion Powerball.

WHEN ROB DELETED ALL TRACES OF BLAC CHYNA ON INSTAGRAM

So, did they break up … or not? That was the question plaguing every pop culture fanatic's mind when news broke that the Keeping Up with the Kardashians star had wiped all evidence of Chyna off his account.

WHEN ROB ADDRESSED HIS RECENT DELETING SPREE

In an attempt to address breakup rumors following that Insta cleanse, Rob went back to Instagram to announce that he and Blac were looking to keep their relationship as private as possible. "It's impossible to have a positive relationship with so much negativity from the media and outsiders and we would appreciate if it everyone respects that," he wrote. Another important update? Kardashian coined a couple name for them: ChyRo.

WHEN ROB POSTED A MEME DIRECTED AT SISTER KIM

Rob is known for having no filter (much like the rest of the Kardashian clan), so it didn't come as a surprise when the dad-to-be made a shocking statement about older sister Kim back in March – referring to the reality star as "the bitch from Gone Girl," complementing the caption with a still of Amy Dunne, the murderer/fake kidnap victim in the thriller. "He always posts things he thinks are funny and deletes and unfollows people," a source close to the family told PEOPLE. "He's so bizarre, he posts and deletes and thinks people aren't going to notice."

WHEN HE ANNOUNCED HIS ENGAGEMENT

After a whirlwind romance that lasted 10 weeks, Rob and Chyna made things official by getting engaged – news the couple immediately shared on their accounts to many mixed reactions from fans and even family members.

WHEN HE ANNOUNCED HE & CHYNA WERE EXPECTING THEIR FIRST CHILD TOGETHER

First comes the engagement, then comes baby! The pair announced back in May that they would soon be parents (and later confirmed they were expecting a girl).

WHEN HE DELETED ALL PICS OF CHYNA (AGAIN)

In July, Rob went on another one of his social media cleanses, wiping all traces of Chyna from his Instagram and leaving a single photo of himself on his account. The action took fans by surprise, seeing as the star is very vocal about his love for the model. Despite Kardashian's decision to rid himself of PDA-packed 'grams, sources close to Chyna said "they're not broken up." "They filmed [their upcoming E! reality show] over the weekend and had an argument," a separate source shared with PEOPLE, adding, "It's hard to see Rob and Chyna actually splitting. Rob is looking forward to becoming a dad. It would take a lot for him to break up with her."

WHEN HE CONTINUED ON WITH HIS PHOTO PURGE

After briefly adding new pics of his fiancée on Instagram, Rob deleted them again. The former music video star made it a point to clear up breakup rumors, however: Chyna bared her growing baby bump on her own Insta account, posing next to the car Rob gifted her.

WHEN ROB POSTED SISTER KYLIE'S PHONE NUMBER

On Monday evening, a tweet from Rob's account shared his youngest sister's cell phone number – twice. "Kylie's # ... I ain't hacked either this is rob dog lol," the first tweet read, along with the phone number and 16 crying-laughing emojis. A second post listed the Keeping Up with the Kardashians starlet's phone number again (an insider says the digits were real). As for what sparked the messages? A telling tweet that followed implied that the Kardashian family allegedly threw a baby shower for Rob – without inviting Chyna.
