The 42-year-old reality star was marking her only brother Rob’s 36th birthday and shared a string of throwback photos to celebrate his big day.

Writing next the collection of memories, The Kardashians star said: “Happy Birthday Robertito.

“I just love you SO SO SOOOO much!!! I wish I could post your singing voice notes on here to show the world your true talents.

“BUTTTT swipe to the last one to hear Robbie speak fake Armenian.”

But eagle-eyed fans noticed that shortly after Kim posted it, one snap was missing.

The picture in question showed Rob and Kim joined by eldest sister Kourtney and their youngest full-sister Khloe while half-sister Kendall Jenner was also there.

But youngest Kardashian star Kylie Jenner was half cropped out of the image – prompting some fans to speculate this is the reason Kim deleted her original post.

One fan questioned: “Kim reposted and took this first pic down. I wonder why.”

Another responded to speculate: “prolly cause she cropped Kylie out or sum… or something was photoshopped wrong idk lmao.”

While another fan noted: “none of these pictures are recent from like this year or last.”

Meanwhile, after years of mental and physical health issues that played out on KUWTK, Rob, the only son of Robert Kardashian and his then-wife Kris Jenner, decided to live his life mostly out of the spotlight.

He was just 20 years old when he stepped into the spotlight alongside his siblings for the premiere of KUWTK in 2007.

It wasn’t until years later that Rob started struggling with his weight issues, and his TV appearances eventually faded over time.

Fans consistently worry about his health, particularly in March 2022, after his sister Khloe liked a cryptic tweet about him.

Rob also appears to shy away from social media as his official Instagram account is run by Jenner Communications, according to his bio.

He even skipped his sister Kourtney’s lavish Italian wedding to Travis Barker, which, according to Us Weekly, wasn’t personal.

A source told the outlet at the time Kourtney’s only brother “really wanted to be there for Kourtney’s special day,” he just didn’t want the extra attention.

Rob did make a rare appearance in an episode of his family’s Hulu show in May.

However, he tried to hide from the cameras the entire time.

Rob was also the only Kardashian to miss out on Kim’s big 42nd birthday bash in October.

A recently leaked email suggested that Rob could be making a return to the reality realm.

Posted to social media, a screen grab of the anonymous email read: “Rob Kardashian’s rumored return to the public eye is true.

“There will either be an exclusive podcast or a Kardashian’s episode with him talking about what he’s been going through and what help he’s been getting.

“[His daughter] Dream’s happiness is the focus.”

Rob shares his only child with ex Blac Chyna.
