Many photos popped out online showing that Rob Kardashian gained weight and some said that he looks unrecognizable. Aside from that rumor, some said that the reality star is so upset with weight gain issue.

In the new photo released, Rob appeared in public and posed for a picture after months of absence in the limelight. According to Classic Lite, the Kardashian star doesn't appear to have dropped much weight.

Extra claimed, "We barely recognized Rob Kardashian when he resurfaced in L.A. this week...Rob has been keeping a low profile since skipping Kim and Kanye's wedding last May. Kim later said that he was feeling uncomfortable and didn't want to be around a lot of people, adding that there were no hard feelings...Meanwhile, Rob's well-being has been a concern for the family."

According to Inquistr, Rob opened up to to his now ex brother-in-law Lamar Odom about his worry on his weight.

"It's just frustrating to me that I'm not happy going out if I'm not in good shape, you know what I mean? Within the next six months, if I don't get this together then I won't want to hang around everybody. I want to, so my mom doesn't cry and thinks something bigger is going on when really it's really simple," he told Lamar.

Lamar replied, "It's okay if there is something bigger."

Some reports said Rob changed his mind to attend his sister's Kim Kardashian wedding in the last minute. There was an episode where their mom Kris Jenner cried over the issue of his son Rob. She said in one of the episodes of "Keeping Up With The Kardashians," "It's the worst feeling in the world when one of your kids isn't in a good place, and I think about it all the time. You don't think [that] it's torture for me to be here in Thailand and have him be at a home? I can't control someone else's behavior, and I've got to learn how to deal with that."
