Feisty Khloe, 29, shamed users, insisting that their ‘bullying’ would lead to lasting mental scars.
Rob, 27, hit out at the trolls first, writing: “So I found out I was trending for being fat… thank you all it literally made my day :)
“To the blogs saying I went to fat camp or rehab LOL then why am I still fat you fools?? Y’all must have run out of real news.
“First, I don’t believe in rehab or therapy or anything of that sort and second I am a grown man and will work on myself when I chose.”
Rob’s big sister Khloe was not happy when she saw her brother defending himself to the Twitter bullies.
She wrote: “I love you @robkardahsian. Some of you are disgusting for calling others names and picking on them.
“You should be ashamed of your self. Your words are cutting deeper than you know and are possible (sic) leaving lifetime scars.
“What shallow souls some of you are. It’s sickening to critique anyone off of their appearance. Grow up!”
The nasty Tweets about Rob’s weight began when he was spotted at LAX airport with the rest of his family yesterday. The famous clan were off to Paris where Kim, 33, and 36-year-old Kanye West are rumoured to be getting married next week.
Obviously appreciating his sister stepping in, Rob tweeted: “and I love you @khloekardashian ...................... but I don’t want to love somebody else.”
