Rob continued his rant on the social site, denying rumours that he had sought help for emotional issues and weight struggles: "i don't believe in rehab or therapy or anything of that sort and second I'm a grown man and will work on myself when i choose," he explained.

"I'm aware that I'm fat that def aint a surprise to me lol and my only therapy will be in the gym anyways had to say somethingggggggggg," the fledgling sock designer added. His sister Khloe quickly jumped into the ring to support her sibling, writing "I love you @robkardashian" and "Some of you people are disgusting for calling others names and picking on them."

"You should be ashamed of your self. Your words are cutting deeper then you know and are possible leaving lifetime scars!...What shallow souls some of you are. Its sickening to critique anyone off of their appearance. Grow up!" the loyal 29 year-old TV personality added.

Noticing his sister's defensive rant, Rob replied "and i love you @khloekardashian ...................... but i don't want to love somebody else." The siblings' words come in the middle of a whirlwind of rumours which suggest that the Kardashian brother didn't want to attend Kim and Kanye's wedding because he was ashamed about his weight having gained a reported 100 pounds in the past year.
