Rob Kardashian is ‘making a comeback’ to Keeping Up With The Kardashians after dramatic weight loss!

Rumour has it Rob Kardashian is going to make an epic comeback on *Keeping Up With The Kardashian *by revealing his dramatic weight loss.

The reality TV star reportedly put on 100 pounds in one year and has now already lost "more than 15 pounds" (a stone).

A source told US Weekly: “Rob has been sticking to the plan Gunnar [Peterson] created for him, and is getting meal delivery from a chef."

More news!

Rob's been working hard to lose weight and with a little help from his older sister, Kim Kardashian, he's been going for long hikes too.

She then also tweeted Rob, who has been battling weight gain and depression for years, "Rise & Grind! Workout time!!!!! With @robkardashian."

And although Rob uploaded the selfie above at the end of August, he hasn’t stepped out publicly since bailing on Kim and Kanye West’s May 2014 nuptials.

Even more remarkable, the brother Kardashian hasn't appeared on the family's reality TV show since 2012!

Another source explained to US Weekly: “He’s not getting paid if he doesn’t film.

“He has a $2 million-a-year contract. He realized he couldn’t give up this huge opportunity.”

Good to see you're on the mend Rob, and we hope to see you soon on KUWTK.

WE MISS ROB.
