The 30-year-old reality star has had issues with his body for some time, and after his recent social media outburst in which he posted explicit photos of his ex-fiancee Blac Chyna without her permission and accused her of being unfaithful and on drugs during their relationship, he has reportedly vowed to shed the pounds and get back the "old Rob".

According to, Rob - who has 11-month-old daughter Dream with Chyna - is "determined to lose [weight] and has already hired a nutritionist and started working out again. His goal is to get back to the 'old Rob' and he's determined to do it on his own ... with no help from friends or family."

The news comes after Rob's mother Kris Jenner recently said the star is "doing great" following his feud with 29-year-old Chyna, which resulted in the beauty getting a restraining order against Rob.

Kris said: "Rob's great. He's working on a new clothing line, and I see him every day because he lives down the street."

Whilst his half-sister Kendall Jenner added: "We're literally on a group chat every single day."

The 'Keeping Up with the Kardashians' star has stayed largely out of the spotlight since his battle with Chyna, and the pair recently came to an agreement over custody of their daughter.

The agreement will see Rob fork out $20,000 a month in child support, while Chyna has, in return, promised to drop the domestic violence accusations she made against him.

Chyna's attorney Lisa Bloom had said before the custody case went to court: "We are attempting to work out an amicable resolution of all issues. If that fails, we will go forward with the hearing on September 18 so that the court will impose long-term consequences on Mr. Kardashian for his vicious online attacks on Blac Chyna."
