It is no secret Rob Kardashian has gained weight, and is doing whatever it takes to get back in shape. Having Internet trolls ridicule you does not help, and the reality star is shutting them up. 

Rob was photographed jetting to Paris yesterday for the upcoming Kimye wedding, taking social media by storm. He decided to fight back in a series of tweets, and even big sister Khloe Kardashian jumped in!

"So i found out i was trending for being fat...thank you all it really made my day," he wrote Tuesday.

"And to the blogs saying i went to fat camp or rehab LOL then why am i still fat u fools?? y'all must have run out of real news," he continued.

"first, 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. 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 youngest Kardashian sister, who recently separated from husband Lamar Odom after four years of marriage, tweeted support for her sibling.

"love you @robkardashian," she wrote. "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!"

There were rumors the future Mrs. West's brother would not attend the "wedding of the century" due to his changing appearance. We are so glad he changed his mind!
