Rob Kardashian Shows Off Massive Weight Loss In New Instagram Photo — See The Pic!

Rob Kardashian showed off his massive weight loss in a new Instagram photo on Friday, November 1. The reality star shared a snapshot of himself and his mother Kris Jenner in their Halloween costumes and he looked noticeably slimmer than he has in recent years.

Rob, 32, went as King Peppy from the animated movie Trolls. He wore green pants, a t-shirt from his clothing line Halfway Dead, a green vest and a pink wig and mustache. Kris was dressed as a skeleton mariachi singer from the movie Coco.

Kim Kardashian's younger brother seems to be bouncing back after a rough couple of years. He battled depression and weight gain, which led to his decision to retreat from the spotlight. The sock designer was also diagnosed with diabetes. He reemerged at Kim's 39th birthday in Palm Springs, California on October 21 and made headlines for his noticeable weight loss.

He was also spotted helping sister Kendall Jenner celebrate her 24th birthday at Delilah restaurant in Hollywood on October 31. Romance rumors began to swirl when he was photographed looking quite cozy with Kylie Jenner's bestie Anastasia "Stassie" Karanikolaou as they left the bash.

Rob has reportedly been implementing various lifestyle changes to improve his overall health. "He is very focused on making changes and sticking with it. He has cut down fast food and has completely changed his diet. He also stopped drinking, which is really helping him. He is feeling a lot better and seeing results," a source dished to E! News. "He is also exercising again and working out with a trainer. He gets together with friends to play basketball at his home court and has fun with that too," the source added.

Rob shares daughter Dream, 2, with ex Blac Chyna. Although the former couple had a nasty split, they are doing their best to amicably coparent their little girl. "Blac Chyna and I are both actively co-parenting and there are no pending or active custody cases," he tweeted in February after they resolved their legal issues.
