Kim Kardashian Hints Brother Rob's Weight Gain 'Not His Best Phase;' 'KUWTK' Star Comes To Khloe's Defense Amid Her Twitter Feud With Amber Rose

While Kim Kardashian hinted that brother Rob Kardashian developed some insecurities due to his continued weight gain, that didn't stop the "KUWTK" star to come to Khloe Kardashian's defense in her ongoing feud with Amber Rose.

"He's not feeling too good about himself these days and he didn't feel like seeing a bunch of people when he'd be feeling uncomfortable, which I understand," said Kim Kardashian in an interview with Love magazine.

"I think everyone just goes through different phases in life, and with my brother maybe this is not his best phase, but he'll grow out of it," Kanye West's wife said of Rob Kardashian's weight gain.

Meanwhile, Rob Kardashian took the cudgels for his sister Khloe after her Twitter argument with Amber Rose over the latter's comments against Kylie Jenner.

"If Amber Rose only knew how bad she is making herself look. And yes, I'll tag the b***h cause adults don't subtweet," Rob tweeted, according to Inquistr.

"Holding grudges and being angry is not worth it. Tomorrow is never promised. Thankful for all of my blessings, family, and friends," he reportedly added.

However, it didn't take long for the hate comments to flood in, which prompted Rob Kardashian to retort: "Wow I have some crazy ass mean tweets from people!!! You guys are insane! Completely."

One of his followers commented: "I would imagine you need thick skin to be famous.. people can be ridiculous."

Another wrote: "I can't believe the mean tweets people send to celebrities they don't like... it's insane."

One woman lent her support: "Some people have too much time. Get a life people! Keep your head up Rob!"

And yet another issued a warning: "You are the one keeping this going now. Don't cry when Amber claps back at you."

It's easy to understand Rob Kardashian defending Khloe from Amber Rose's Twitter digs since his older sister took him in when he allegedly shunned away the rest of the family following his weight gain.
