that featured a throwback photo of her best friend Malika Haqq, 39, closely hugging Rob.
Alongside a broken heart emoji, the Twitter user captioned the post: “We were robbed.”
The Keeping Up With the Kardashians alum later liked the tweet, which led some fans to believe that Rob had passed away.
One Twitter user wrote: “Literally thought he died…”

Another added: “Don’t f**king scare me like that.”
More fans admitted to misunderstanding the post, as someone else wrote: “Don’t f**king scare me like that.”
However, it appears Khloe liked to tweet to imply she wished Rob and Malika had dated.
Other KUWTK fans shared similar sentiments, with one person writing: “They should have got together.”
An additional person chimed in: “I always wanted them to at least try to date. Friends first make the best relationships later.”
RESURFACED CLIP
Khloe unintentionally sparked the rumors after she was slammed for making fun of her younger brother's weight gain.
Earlier this week, a KUWTK clip resurfaced of Khloe and her friend Jonathan Cheban joking over Rob's appearance.
In the clip, Khloe sat with her sister Kourtney in the kitchen and asked: "What am I going to do?
"It's the first thing [Rob's] ever actually immersed himself in."
Jonathan replied, laughing: "Well, besides the two refrigerators."
Khloe burst out laughing and covered her face with her hands.
After the clip resurfaced, Rob's fans rushed to Reddit to slam the pair for their "mean" comments.
One wrote: "The nerve of Khloe to laugh when she knows what Rob is feeling like. Such a mean girl interaction."
Another added: "I hate that some people have this sick reversed mentality that men can’t be body-shamed or have feelings."
"Imagine hearing someone talk about your sibling like this and laughing. I would knock someone out," a third commented.
ROB'S PRIVATE LIFE
Unlike his famous family members, Rob prefers to stay out of the limelight and isn't super active on social media.
He suffers from diabetes and has had numerous hospital visits since his diagnosis in 2015.
Rob has struggled with his weight for years and is believed to have weighed almost 300lbs at his heaviest.
