"So i found out i was trending for being fat," Kardashian wrote a day after he was photographed looking a bit chunkier as he arrived to LAX with his mother Kris Jenner. "Thank you all it really made my day :),"he added.
The 27-year-old reality star continued his rant dismissing reports that he went to fat camp.
"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," Kardashian tweeted.
The Dancing With The Stars alum when on to say that he is "aware" that he's gained weight and that his "only therapy will be in the gym."
Kardashian's sighting at LAX on Sunday comes as he and Jenner headed to Europe for Kim Kadashian's upcoming wedding to Kanye West.
