Khloe Kardashian is under a little heat after she shared a snapshot on Instagram Thursday that was noticeably missing her younger brother Rob Kardashian.

In the picture Khloe rocks a black t-shirt with gold writing that lists her mother, Kris Jenner and all of her siblings, sans Rob. But who is added is her brother-in-law, Kim Kardashian's husband Kanye West.

"Kris & Kim & Khloe & Kourtney & Kendall & Kylie & Kanye." it reads.

Of course fans immediately took to the picture with questions of where Robb's name was.

"WHERE IS ROBS NAME??"

"Poor Rob always left out".

"Awww, where is Robert?"

"You are just sad....fake lives real problems".

But others made it clear she wasn't trying to diss Rob. The shirt clearly only lists the names that start with the letter "K." After all, Kourtney's longtime boyfriend Scott Disick's name is missing as well. And most fans know that Kourtney and Disick are pretty much inseparable.

"Obviously it's only 'K's".

"Kanye is a 'K' Scott isn't...If Rob's name was on here then I would taken that more offense as he isn't a 'K' and having him on the end of the top makes him look as if he is left out more than his name not being here at all."

"They should have left Kanye out of it like the other guys, even though he is a K. It's not like he is one of Kris' children."

Other fans joked that Rob should change his name to "Krob" so he can make the cut next time.
