Rob Kardashian is back and he looks healthier, not to mention happier, than before. The only Kardashian son returned to the spotlight and joined his sisters for the celebration of Khloé Kardashian's 36th birthday.

Rob Kardashian has been away for a long while after he suffered from depression and weight gain. He, reportedly, started a weight loss journey and now returned to show his major transformation with a huge smile on his face.

The 33-year-old television personality looked like his old self in the photos shared by his mother, Kris Jenner. Although the day was all about Khloé Kardashian's birthday bash, fans could not help but put their attention to his brother's return.

In one of the momager's posts, he shared a photo of his son having fun with her sisters, Kendall and Kylie Jenner and the birthday girl herself. She simply captioned the snap with "four of six," referring to the number of her kids in the photograph out of their total.

Rob Kardashian also shared photos from the party on his own Instagram account. He had a snap with Khloé Kardashian's baby daddy, Tristan Thompson, along with another pal. He also had a picture while talking to Scott Disick, and another one with Kourtney Kardashian.

The father-of-one looked happier after his successful weight loss journey. He showed his incredible results by wearing a pair of black jeans and sweatshirts, which were similar to what Khloé Kardashian and Kylie Jenner were donning.

Rob Kardashian has been away from the spotlight for a few years. He also rarely shared photos of himself on Instagram. In fact, before he posted pictures from the party, his account was full of snaps from his younger days, his daughter Dream, and other posts where he could not be seen.

Despite his absence, a source told Entertainment Tonight in March that he was doing "really well." He continuously worked hard to stay healthy for himself and his only daughter.

Although he was not seen with his KarJenner family in public, they indeed have a great relationship. He also truly values family time. He loves being around his nephews and nieces and spend time with his three-year-old kid.

Now that most of them already have kids, who are growing up together, their family becomes closer and "tighter than ever." In July, Khloé Kardashian and Scott Disick revealed that Rob Kardashian had been spending his time working out at Kim Kardashian's house.
