Rob Kardashian, the brother of the infamous Kardashian brood, is out and loud again on his social media accounts after months of hiatus from his social media circle. Rob Kardashian has hit back at critics who have been calling him names for his weight increase.

The reality star responded to his critics on Twitter on Tuesday morning, May 20, after trending on the social networking account. Pictures of the reality made rounds on the internet after photographers snapped him after his weight increase at the Los Angeles International Airport on Monday, May 19. This is the first time Rob has been pictured after his self-imposed hiatus from the media.

Rob Kardashian was in the airport along with his mother Kris Jenner to attend his sister Kim Kardashian's upcoming wedding with Kanye West in Europe.

"So I found out I was trending for being fat... Thank you all, it really made my day. : )" The "Keeping up with the Kardashians" star wrote on Twitter.

Rumours have been circulating around the internet over the alleged forcing of momager Kris Jenner on Rob Kardashian to attend a fat camp to trim down his weight. However, Rob was quick to rubbish the rumors by saying:

"To the blogs saying I went to fat camp or rehab, LOL." The star tweeted. "Then why am I still fat u fools?? Y'all must have run out of real news." The star further posted on his Twitter account.

"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," the star further added on his account. "I'm aware that I'm fat that def ain't a surprise to me lol... My only therapy will be in the gym, anyways had to say somethingggggggggg."

Known to be a supportive brood, Khloe Kardashian took her support for Rob on Twitter by saying:

"I love you @robkardashian," she wrote on Tuesday. "Some of you people are disgusting for calling others names and picking on them... You should be ashamed of yourself. Your words are cutting deeper then you know and are [possibly] leaving lifetime scars!"
