Rob Kardashian Reveals Massive Weight Loss During First Family Pic In Years!

Rob Kardashian just dropped some huge news ... he's back, baby!

The 32-year-old former "KUWTK" star posted a photo of himself on social media Friday night for the first time in years, and he showed off a much slimmer frame from the last time he was seen in public.

Wearing a pink wig with a fluffy pink mustache, Rob dressed up as King Peppy from the movie "Trolls" for Halloween and was seen smiling into the camera alongside his mama, Kris Jenner.

Jenner stood behind her only son and showed support, while she was dressed in an immaculate costume paying homage to Dia De Los Muertos.

He Dressed Up With Dream

Probably the biggest reason for Rob Kardashian coming out of his shell is his daughter with Blac Chyna, Dream.

Dream and Rob actually teamed up on a Halloween costume this year. He went as King Peppy and 2-year-old Dream went as Poppy from the movie, "Trolls."

Even though Rob has been absent from the public eye for years, he kept up on social media with Dream and regularly posted pictures of his daughter.

He even shared the birthday party that Dream helped throw back in March. Rob regularly has St. Patrick's themed birthday parties, and Dream was the main coordinator behind the shamrock-packed bash, which went down at Khloé Kardashian's house.

His Family Reacts

Immediately after Rob's big reveal, everyone flooded his Instagram page with comments, including some of his biggest admirers.

Big sis Kourtney Kardashian was one of the first commenters, and gushed, "Obsessed with you."

Scores of fans wrote, "Looking good," while others commented that "Rob Is Back!"

Within 2 hours of posting, Rob had already racked up near 100,000 likes on the photo.

It was clear that Rob had the support of many fans who all were excited to see him feel comfortable enough to share the personal moment.

Getting Fit

Getting camera-ready has been a long process for Rob, but one that he's stuck to for months.

Back in June, he finally made the decision to change his life and shared the milestone on social media.

"Day 1 all good," he wrote while showing off a home gym setup, which included a weightlifting machine and a basketball court in the background.

It appears basketball was a big part of Rob getting back in shape and he was holding games at his home court.

He even showed off one of the games where he apparently emerged victoriously.

"Just beat my fellow USC ALUM@iammsuzyone on one ,,, USC let’s go ‼️❤️💛😭😭😭 take the L don’t lie. I am the midrange king."

Why He Went Away

It's been over 3 years since Rob made a public appearance, and has struggled with being seen by anyone but close family and friends.

Back in 2016 Rob was still with his baby mama, Blac Chyna, but a volatile breakup caused a mental downfall for him.

In court documents, Rob has claimed that mental anguish from his turmoil with Chyna, especially with their defunct reality show, "Rob & Chyna," caused him so much stress that he could no longer participate in reality television.

Maybe now that he's back on the right path, and has patched things up with Chyna, he'll soon make a return to TV.
